Opening garageband file on ipad from iphone

I created a garageband file on ipad, which i then opened on my iphone. Now, i can’t open this specific file on my ipad anymore, and a message on how this file requires an updated version of garageband appears. My app is up to date, and i have never had this problem before (i use icloud to open garageband files on my iphone and ipad). I can still open other garageband files, on my iphone and ipad, without any problem.

Could someone please help me?

Thank you.
