Garageband for iPadOS 16 or iOS26 won't save dubstep loop collection as a song.

Garageband for iOS and iPadOS seems not to save Dubstep loop collection locally or on the iCloud. Initially it worked with EDM.band but now when I create a new song and load the dubstep loop collection and save it it does not get saved.

I tried reinstalling and clearing up Garageband but it still won't save.

Can somebody help?
