Adding my scores to my groups

MuseScore 871c8ce
Earlier this evening I added 4 new private scores to my MuseScore account. I then added them to the choir group they needed to go in. The green box told me that I had added them to that group (DandDmvc). I then went to the group, but the scores hadn't been added.

I repeated this about 6-8 times. I logged out. I deleted and reloaded one of the scores. I tried adding them to a different group. I removed them from the group. All the actions appeared to work on the My Scores page, but none of the scores appeared in any of the groups I tried to add them to.

Has something changed with adding scores to groups? Is this affecting anyone else? I'd be grateful for any insight into this issue.

Thank you for your excellent MuseScore work.

Cheers,
Pete
