BUG - Can't undo inside nested comps if parent comp is open.
I've noticed for some time that there is a bug in Premiere where undo history for a nested sequence does not get populated, in other words, any application of the "undo" command will only undo actions in the parent sequence. This can be mitigated by closing the parent sequence prior to working on the nested one, but still, this is unintuitive and annoying.
Until last week, I was using a Mac Pro (Mid 2013). I've since switched to an Alienware PC, and the issue persists on both systems.

That explains a LOT of the issues I've been having. It's a shame that Adobe developers never seem to read any of these posts or attempt to fix anything.
