New Composition isn’t black screen but instead scene from an old Project in AE CC2018 [Windows]

I have a problem with creating a new composition. When I create a new composition, it is supposed to show a black screen, but when I do that, one of my deleted projects I've previously worked on pops up instead of a plain black screen. I've uninstalled AE and redownloaded.
