I believe you may have run a script “claim” individual items on your account from one of our “mega” bundles. This is not necessary and can cause issues with loading your entire library since it floods your primary library list. If you want I can reset your library to make it so only items you have explicitly downloaded show up, it should resolve the issue you’re having.
We intend to address bundles in our next app update to make it easier to access the mega bundles, which use a different representation in our backend.
