It's certainly a bug and I'll look into addressing it. The easy answer is just to fix what page is entered into the dialog so that it's relative to the current file. I like this approach better than allowing the user to enter a page relative to the total number of pages in the song among all files because the user could enter a value outside the range of pages for the current file, and it would involve additional error checking and handling.
