When did you add Command-R to do Remove Overlap? Or is that an error? I do not have that set up in my custom shortcuts either.

Mine is Shift+Command+O (default). Command+R is a re-run of the previous filter, so it’s likely that you just did so.

Ah! Thanks for the explanation. I didn’t think of that.
