Cannot delete last page

[Bingo]

This is just a version of the document, I'd need instruction on how to fix it

I had someone make this strange custom document and it worked out fairly well... but the last page has a different footer and won't let me highlight and delete. I can't figure it out. When I try just highlighting and deleting, it replaces my previous footer/header with the one I don't want and mucks it up.



Thank you!
