Click a part of "E" in the image below on the Synth Rack to get back "Insert Soft Synth Options dialog" and then check the box "Ask This Every Time".
Is this works?

As one possibility... USB cable problem?
As a test, try to connect to another USB port?

I did look into this forum system on Invision Community site and found Guide page "General Posting Control". There is a description about upload images at "General - Maximum Image Size". So I can't understand why this Cakewalk forum does not show images with original size even if clicking thumbnails...

Have you tried the resize options ? Double click on the photo after it is inserted in the comment box.

I didn't know that so tried it but seems max width is 500px.

"vst Arpeggiator plugin" what you say is name of plugin?
Is it really VST plugin, not MIDI FX plugin? 
or Maybe VST instrument, not FX?

1. Exit Cakewalk by BandLab
2. Log Out of BandLab Assistant by clicking the gear at the top left and choosing Log Out
3. Log back into BandLab Assistant, and run any updates if prompted
4. Go to Apps, find the Cakewalk by BandLab logo, and click Open. (If there is Cakewalk update, update it.)

If it's still not work, try again with running BandLab Assistant as administrator. If that doesn't work, contact support.

Right click on the clip and then "Rename Clip".
You can also edit selected clip name at "Clip properties" on Inspector.

 Is there a  way to suggest perhaps adding this 'feature' to a later release?

You can post feature request to Feedback Loop.
There is similar request already.

Maybe  this...?

@Toddskins I just installed it without uninstalling and deauthorize. Seems no problem.

Unfortunately our current Melodyne version 4.2.2 has an error which, in certain constellations, when the application starts, displays a “version is expired” message and quits again. We are truly sorry that we missed this bug.

In any case you should replace your current Melodyne installation with the newest version 4.2.3, which we have uploaded. You can find the installer in your user account: https://services.celemony.com/cgi-bin/WebObjects/LicenseApp

The good news: documents you have saved with the 4.2.2 version are not affected by the problem in any way. After installing the new version you can continue working as always.

We would like to sincerely apologise for the application error and the caused inconveniences and ask for your understanding.
 

Make sure "Auto Track Zoom" is not checked in view menu on the track view.

Probably, Selection markers in time ruler?
Whenever a selection exists, the selection range is displayed in the time ruler.
If you need to rid of it, press "Ctrl + Shift + A" to unselect all or just clicking empty part of clips pane.

Have you click the Show/Hide Bus Pane button  which is located at the bottom of the Track view to show Bus Pane?

For now, there is no update message on BandLab Assistant. (BA is still v5.0.4 here.)
So I guess they are temporarily stopping it. But direct downloaded installer from BandLab site is v5.0.5

That's new and other issue, not related to an issue on this thread.
Let's talk about it on the thread what you posted already.

FYI:
For now, there is no update message on BandLab Assistant, btw. (My BA is still v5.0.4) So I guess they are temporarily stopping it. But direct downloaded installer from BandLab site is version 5.0.5

Yes, the update message is gone now...

Today, I get Update message on BandLab Assistant. So I did update and got "Update Failed" and "Please Download and then Install BandLab Assistant manually."
I downloaded "bandlab-assistant-windows-latest" and then installed it. But BandLab Assistant is saying "A new version of BandLab Assistant is available for update" again, again, again...

Seems downloaded bandlab-assistant-windows-latest.exe is ver 5.0.4.
I had ver 5.0.4 for a long time. Why do I get update message on BA? 

I tried on my another PC and getting same results...

Did you check replies on your similar post?

Seems that plugin "Absynth" may be sending somehow message to the host and Cakewalk is responding by treating this as an edit change and dirtying the document.
I believe @Noel Borthwick can look into it.

It would be nice the Tap Tempo module with "Set (to the whole)" and "Insert (to Now time)" buttons.

I remember having same problem but it's happened with a project which has only MIDI tracks and it's already fixed on 2019.05 build 31.  So I think that problem you are having is caused by other thing. But maybe there is some hints on this thread at that time.
