Unable to delete shared collection links

Posting on behalf of a user:

I’m getting the message that I’m out of the free tier because of share links in a collection.
But when I’m checking my usage stats I’m still under the 25 links.

I can’t find any collection or option to unshare or delete this collection that causes this issue…
