CCleaner "Exclude" not working

I am trying to exclude certain files from being cleaned, but it isn't working properly. I've added the drive and folder to the exclude window, set the file extension, but it still deletes the file.

I have "Custom File and Folders" selected when cleaning. Any ideas why it seems to be ignoring my custom exclusions?

A bug, maybe? Should I post in the bug reports forum?

I see you have,
