Sheet music not showing up in groups

Hi, I have uploaded some scores as unlisted but they came as private. I edited to change private to unlisted. I added them to a group - it said they had been added. Went to the group - no scores!

If I 'manage' groups, it tells me there are scores linked to the group but I cannot see them / access them.

I use musescore for my choirs - hence they are private groups - I used to be able to see the sheet music. Any ideas?
