Playstation (PS5) Highlight Not Saving

Is the bug known about Highlight that cannot be saved?

I think around a week ago I wanted to save a highlight. I didn’t check on the ps5 storage (still plenty of room) if it was actually saved. A few days ago I checked and I was missing a couple of highlights/potg. So, the last 3 days I always checked if the saving works again - even after the latest update.

Kind Regards to the community.
