Yes- I am having the same sort of problem too, and like you it is making me very wary of the editor. I have been making edits tp performances while the kemper is on perform mode but amps keep moving to different rigs. I changed the kemper to edit mode but if I am editing performances in Rig manager, I don't know how to save the edited rig in the performance I am working on. Very frustrating and also dangerous if you have a gif coming up .
