Deleted Notes Reappear Every Time Scrivener is Opened.

I tried searching but couldn’t find this question, so I apologize if it’s already been asked.

I have some files in Scrivener that have a lot of notes attached. I wanted to transfer the text to a different Scrivener project without the notes. I transferred the file to the new project and deleted the notes, but every time I open Scrivener, the notes are back. I’ve tried everything I can think of. I even cut the text and pasted it into Notepad, deleted all the notes, and pasted it back into Scrivener. Is anyone else having this problem?
