How do I delete a score when its deleted from musescore.com?

Hello, this is my first time posting here to this forum. So I just made a piece on Musescore, I decided like right now that I wanted to delete the score. How would I go about doing that? There is nothing that says it on the application itself, so I looked at the score on musecore.com, and i pressed delete, its gone from the musescore.com page, but not on the application that allows you to make scores. and when I click on the score from the app, it says that "the score does not belong to this account, to access this score, make sure you are logged in." Any help so it can be fully erased from this account will be helpful. If you want me to clarify anything just ask me.

Thanks!
