PT is Forgetting/Losing Locate Points info!

[StrangeRover]

Hi All —
A big part of my workflow for the past few years has been using Locate Points to store Track Visibility settings. This allows me to quickly show all my drum tracks and ONLY drum tracks, then quickly switch to viewing all/only guitar tracks, then vocals, etc.

I'm working on a session right now that keeps losing track of my Track Visibility settings, so when I recall Locate Point 10, for instance — expecting to see all my drum tracks —*I might get nothing... or I might get a bunch of tracks on the screen that are NOT what I'd saved. Could be some drums plus other stuff... could be entirely different stuff. It seems completely random.

This is really slowing my flow. It cropped up just last week. At the time I was on PT 2021.3 but now I'm seeing the same behaviour from 2021.6
