Hi,
We have a total of approx 15 records that were shared with a team of users. The owner of this team is now gone and his user is inactive. The team got deleted and now the records are now reshared with another team and users, but when we click on share with on the top right of the record itself, it will show up as it is shared with this team still but no Team Name shows up. See the exemple below of the share being still present (visually speaking) but in the background the record is not shared and team or user does not have any access.
