I get the following error while trying to delete an account:

"Your attempt to delete (Name of Account) could not be completed because it is associated with the following accounts. If the following table is empty, it is because you do not have access to the records restricting the delete."

And the table shows only 1 record, that record is the account I tried to delete (verified by ID).

The account is not associated to itself in any way with a custom lookup or elsewhere. I'm not sure what could be causing this I'm using an Admin user with all of the delete permissions you would normally need.
