Interface cannot be re-implemented after removal from blueprint

If an interface is removed from a blueprint and an interface function is transferred to a local function, the interface cannot be re-implemented in the blueprint.

1. Open Editor (any project)
2. Create new blueprint interface
3. Open interface to create a function
4. Compile Interface
5. Create new blueprint
6. Go to Class Settings>Interfaces>add>new interface
7. Delete new interface from class settings>interfaces by pressing x
8. Transfer function to local function when prompted
9. Attempt to re-implement interface in blueprint

Results:
If the same interface is selected, the interface will not appear on the implemented interfaces list.

Expected:
Interface is implemented in blueprint.

Attempting to modify an interface. Assertion failed: Pin == NULL || Pin->Direction == EGPD_Output
