I am a "Pending Changes Reviewer". I reviewed and rejected the edit on this diff:
https://en.wikipedia.org/w/index.php?title=Action_Bronson&diff=prev&oldid=688741846
Later, another editor did an undo on an edit previous to the edit I undid and that undo got "charged" to my username (I got a double-badge alert re: the undo). Here is the diff for the undo that was erroneously charged to me:

Here is the diff where the edit was made that the 2nd editor undid:

Note: this edit came before the edit I reverted.
This is where I pick up the edits for review:
