Shared "ID's" for games

I have a weird problem where some separate games are labelled as the same project.
This is probably because the projects are copies of each other.
The effects include all the stats of all the games combining, and only one of the projects being able to be on at a time.

Is there anyway to fix this?

Are you saving the project as one of its own? go on the file and click on “file>Save as”

Thanks for the help!
