I have noticed 2 intermittent bugs in the Color wheel Keyframes.
1) If you alter the slider value on keyframe #1, move to keyframe #2 and adjust that value, then return to keyframe #1, the value you had previously changed is no longer there. It has reverted to the previous state. The only way to guarantee the setting of a keyframe value is to shut down Premiere after each keyframe change and then reopen. This has ocurred occasionally since perhaps May or June, I've noticed.
2) As of 7/20/23, Ive noticed that on color wheel keyframes, the crosshair on the color wheel will move in a looping arc from one keyframe to the next rather than a straight line between the 2 keyframed points. I can't change bezier or linear options on the keyframes. They are greyed out. I don't know if this is a linear/bezier bug or something else. Haven't seen this before but it is a very destructive bug.
