Lumetri Color undoes changes when moving along or off the clip

I change a setting (sliding, typing, it doesn’t seem to matter) on Lumetri Color, and then it occasionally (seemingly inconsistently) just undoes the action when I move the playhead. It doesn’t seen to matter what the setting is, the format of the clip, or how I change the setting. Sometimes it will be just the last setting, sometimes it will “undo” to when I first selected the clip to make the changes.

I have been back over clips I have previously changed, after changing more clips, only to find the settings have reverted to an earlier point. Very frustrating!
