adding relationships


I just added a many to many relationship in the studio within accounts to accounts. I named it “dealers” and the other side “customer”

Now after saving the relationship in Studio under Accounts it disappears into thin air. I cannot find it anymore in the relationships list to be edited.
Whereas I find a subpanel in Accounts with Dealers.

But the subpanel is not shown when I open Accounts.

Can someone shed some light into this topic?
