can't update from macOS 10.15

My macbook pro 15 inch from 2017 can't update from any of the recent macOS betas. My macbook is on macOS 10.15, and can't update. Apple just released 10.15.5 beta 5 (May 20, 2020) and I just tried upgarding to that after reinstalling the beta profile, but it doesn't update, my macbook says that it's up to date with macOS 10.15. Any help with this issue would be appreciated.
