Lumetri Color doesn't retain adjustments after clicking away from clip

Latest Windows, GeForce Studio Drivers, Premiere, etc. installs.

• Apply Lumtri Color to any type of video clip, any codec, any frame rate, any size, etc.
• Adjust settings, sliders, LUT, etc.
• Click away from clip or choose a new clip
• Lumetri settings on previous clip revert to a previous choice
• Happens maybe 1/10th of the time

Simplified example:
Clip A, adjust Lumetri Color values to: Temp +2, Tint -3, Exposure 3
Adjust Clips B, C, D, etc.
Return to Clip A, adjust to: Temp -10, Tint +10, Exposure -1
Deselect Clip A
Temp is now +2, Tint -3, Exposure 3

Unsure if the new "wrong" values on Clip A are identical Clip A, B, or C.

Trashed prefs. Reinstalled. Cleared cache. etc etc etc. All the usual sh!t.
Anyone have any idea what's going on?
