I got many such ModBot edit notes today.
What I did is open track artist credit editor popup in release editor, went to credited name, selected all, delete.
This has always been the fastest way to remove some artist credit, that is to say, to revert to using the plain artist name.
But now it seems that this technique, is still correct for the display but when I submit the release editor changes, it ends up buggy:
> The credited-as name in an artist credit cannot be empty
Where I see "Andrew Philip Carroll as" (should not be this "as").
And Edit #71421415 - Edit medium will also fail as it shows the same issue as above failed recording edits.
