Phantom external storage

I have a folder showing up in my nextcloud instance that shouldn’t be there. It is from an external storage that should have been removed. It doesn’t show up in the settings page, but does show up in the files app and the client syncs it to my computer.

It appears in the oc_storages table and I guess the fix is to delete the entry. I’m just wondering if it is safe to do so before I go ahead and do it.

Can anybody advise?
