I have the reports in zip format, but can't attach them. Files are gray'd out. Am I doing something wrong?

Where is the upload window? Sorry, but I'm new to Developer Forums. I tried clicking "Reply", then the "paper clip", then "Add Files", but when I try to select the files, they are gray'd out.

Will there be any update on this issue? Does anyone actually review the feedback?
