Selection not getting dark

[Pelle Andersson]

Usually when I select something in the arranger area the selection gets darker/shaded and helps me see what's going to be selected.
But in my latest project that "function" isn't there any more!? My eyesight isn't 100% so it's quite helpful.
And the arragement doesn't slide over to the left when I reach the end of the arranger window at the right side.
I included a video of how it looks when it works. How do I get it back?
I've now also included the "not working" video!

Make sure the lower left button in the Select module (must be sized large to see them) to 'Select Events with Sections' is enabled.

That... and I don't see any "arranger" sections in the Arranger track.  Once you add one and select it, the affected track sections will get darker.

Thanks for helping me out! When I got back after dinner after an hour or so, it worked again. Don't know what happened? A bug?
I've had this problem before but assumed I mistakenly hit a kbd shortcut, but it doesnt seem to be the problem?
