There are a couple of things still available that often just don't work at some point. If they could fix them, they would. There is a time when you have to just move on.
Do you care if it throws the tempo/beat/measure off or do you just want it added for the export? I usually do some post processing in Cool Edit like adding some empathy silence. Adding that via Cakewalk could be useful but adding "time" could have some effects to the timing.
Check out AZ Web. It’s the basics but works .

Try selecting the tracks you want to change and then press CTRL, hold it and change one of the tracks. This works to change multiple tracks at once for many parameters. See if it works for your change.
I recall Noel saying there was some architecture challenge (or limitation) to doing this. I agree, it would be nice. It might be on their to-do list though.
At least rule out that the CPU is not overheating and throttling. Get something like Core Temp. You have to eliminate all possibilities. I had this issue on my laptop. And for some reason recording increased the CPU temp and it hit it's limit and I started getting static.
Just a thought.
Lol.
I meant something like clicking on the Arranger section and selecting Export to Wave or Save as .cwp. I know I can selected and go through the export toolbar or advanced export.
Just a thought. I don't really need it.
