PSE 2018 potential bug with face recognition

When PSE2018 organizer finds a new face and shows a suggested name for the face, it presents it in the following format:

"Is this Jane?" followed by a check mark and an X.

You can click on the check mark to confirm, but the X is never clickable.

If the face is not "Jane" but say "Jill" the only workaround I found is to click the checkmark, then re click the face again and manually change the Jane to a Jill
