I made a new sister group but added the wrong members so I deleted the group bc I didn't want to wait a year to move ppl around again. I then remade the group but under a different name and it was all fine.  but I noticed the old deleted group never disappeared from the group roster when you move idols into groups. I thought this was weird, but the full mode didn't show the group as existing. Later, I remade the same group that I originally deleted under the same name. I wasn't paying attention and I added the members to the deleted group and now my idols in that group exist but are inaccessible in full mode even though I see them in compact mode.

Has anyone else had this problem?
