Cannot unapprove a WordPress comment

Question

My client approved a comment in WordPress that she shouldn't have. I cannot for the life of me find a way to get rid of the approved comment, and it appears that there really isn't a way.

I can sort the approved comments, but nowhere is there a checkbox by a specific comment to delete, unaprove, edit, spam or access/modify the comment in any way.

Does anyone have a workaround for this? As you can see by the screenshot, I can narrow down the list to just the one comment, but that is it.

Checking the boxes and using the drop-down menu doesn't actually affect the comment.

Answer 1

See that bulk actions dropdown in lower left? Choose your action there and then click Apply

Answer 2

We finally figured this out. The comments that could not be deleted were imported with posts/comments from a blogger site. These comments were not attached/related to any posts though. So they had to be hand-edited out of the database.
