Incorrect field label on self-link relation

Given a table has a one-to-many link to itself
When the user views Details > Relations
And clicks on the relation
Then the incorrect field name is shown

Example:

Create table “Items”
Add link field “Subitems1” one:many with table “Items”
Observe that the relation is “[Items] Items - has many - Items [Items]”
Instead of “[Items] Subitems1 - has many - Items [Items]”

Create table “Subitems”
In table “Items”, add link field “Subitems2” one:many with table “Subitems”
Observe that the relation is “[Items] Subitems2 - has many - Items [Items]” as expected.

In a link to self, the “Subitems1” field is not referenced in the relation, even though it is the field used to create the relation.

Link to self with incorrect field label:

Link to another table with correct field label:
