Project panel sort order reverts to "Frame Rate" column after closing and reopening projects

Hi there, I'm hoping someone has discovered why this might happen as I haven't found a solution in the forums, or anywhere else online. As the subject line suggests, the issue I'm having is that every time a Premiere project is opened the sort order in the project panel (in list view) reverts to "Frame Rate" and not "Name" which becomes an issue when you are using footage with different frame rates, but want the project to be sorted in name order.

It's particularly annoying when I've had it sorted in name order and then the next day I don't realise it's reverted to frame rate order and then wonder why the chronological order of the footage is all over the place.

I have tried saving custom workspaces with the project panel sorted in name order, and I've tried saving custom metadata settings, and custom view settings in the project panel. No matter what, if I save and close and then reopen any project, then the sort order reverts to “Frame Rate”. Sometimes it has opened to something else to the right of the “Name” column such as “Proxy”, but mostly just “Frame Rate”.

This issue has been happening with brand new projects, and old projects, and on at least 8 different Apple machines I work with, including iMacs and Mac Pros running macOS Mojave and an M1 Mac mini running Big Sur. This issue has been happening consistently over multiple versions of Premiere for a long time now, and I first noticed it with CC 2019, but currently I’m running Premiere Pro 2021 v15.2.0 (Build 35) and this issue persists.

If anyone has any clue why it may be happening I would love to hear it, as so far I feel like I’ve reached my limit of problem solving as to what the possible cause/solution might be. The only consistency I’ve found is that when a project is opened then it will revert to sorting the project panel using whatever column is next to the “Name” column, and it doesn’t make a difference which column you had everything sorted by when you saved and closed the project, it could be”Name”, “Media Duration”, “Video Info” etc, no matter what it will revert to “Frame Rate” or another column right next to the “Name” column.

Thanks in advance for any clues on how to fix this problem!
