First, let me clarify: it is possible to report the page as a whole, or individual edits.
This depends if you used the Report link from the main tab, or from a history action. If a page is reported, it doesn't refer to a particular edit, because the entire page (or the current version) needs to be reviewed. This is working as designed.
When I report a page here, and separately report an edit here, I see that the message for both reported pages and reported edits use the word "page" - however, the link the message includes for review is correct. If an edit was reported, the link points to the specific edit.
