Endpoints are 'undefined' when adding from 'My Interfaces' tab

There seems to be a possible issue when trying to modify an existing L2 circuit and adding and endpoint on a port that a workgroup owns from the "My interfaces" tab. We tried modifying an existing circuit by modifying the circuit, clicking "new endpoint" then adding an endpoint on (which the workgroup owns) via the "my interfaces" tab. The port shows up as "undefined" and the modification cannot be saved.

I updated the ACL to have an entity and added the endpoint by searching for the entity rather than by going in the "my interfaces" tab, which let us modify the circuit successfully. The "undefined" port issue only comes up when modifying existing circuits, not when adding new ones.
