Panel short-cut key reassigned by Premiere with every project opening

Good day,

This is a weird one and has been occuring since the newest Premiere update. By default, Premiere is generally assigned Shift+5 for Effect Controls, Shift+6 for the Audio Track Mixer and Shift+7 for Effects.

I use a custom Shift+6 for Effects (so I can easily bounce back between Effect Controls and Effects). As for Shift+7, anything goes (like Lumetri Color).

So everytime, and I mean "everytime" I open up a new project with Premiere, restart Premiere, reboot the computer, create a keyboard layout preset, or even 'reinstall' Premiere, everytime, did I mention "everytime" — Premiere reassigns Shift+6 to the Audio Track Mixer and Shift+7 to Effects.

Unless I am missing some inconspicuous setting in Preferences, this has the workings of a program bug.

But it gets even weirder! After I re-assgin Shift+6 to Effects for the unteenth time, I then re-assign (if I even feel like it) Shift+7 to the Audio Track Mixer. However, when I press Shift+7, the Audio Track Mixer panel, uhm, does NOT open. It almost seems like it is a short-cut key to panel assign bug, and the Audio Track Mixer panel is a more specific part of the issue.

So is there some Preference setting I am missing in Premiere? Is there a work-around so that everytime I open up Premiere, Shift+6 is always assigned to the Effects panel? Is there a deepfile I can access on the backend to make this short-cut key more permenant?

Thank you for any help you can provide.
