I have a relationship that only exists in the schema of my graph

Hello,

My problem is the following, I write:

MATCH (:District)-[]-(:Department)

and it returns me zero data, but if I write

call db.schema.visualization()

In the schema of my graph it appears that this relationship does exist, so I need to remove it from my schema but I can't find a way to do it.

There is an issue with that method that it is not accurate.
