I have a Doc Set I can not delete. I've tried to delete it via Windows Explorer (in case that would help) and via the Content and Structure menu, but to no avail.
As you see in the pictures below, Sharepoint thinks there are checked out or locked documents. The folders are actually empty. There were 7 folders within the Doc Set, I have deleted 4 of them, three remain.
Any ideas as to what could be causing the error message?
