Project Edits Reverted: Seeking Help with Wireframe Issue

Hi team, I've been working on my wireframe every day for the last week or so. I was in it this morning and no issues. I just went back in now to upgrade to a team account and make a duplicate of the project, and the project shows I haven't made an update in the last 4 days. All my edits & copy are reverted back to the original AI generated versions. Please help me!
