There might be two lookup fields, the second one depending on the first one.
Changing the first one, a different behavior is observed, depending on the interface where the change is being done:
Classic UX - Changing the value of the first field and saving, the second field is cleared out.
New UX - Changing the value of the first field (automatically saved), the second field persists.
STEPS TO REPRODUCE:
1. Log in to the New UX.
2. Add the Department and Location fields to the Projects Grid or into a Blueprint.
3. Change the value of the Department.
Expected Results: The Location is dependent of the Department. Since the Department is modified, the Location should be cleared out, like in the Classic UX.
Actual Results: The Location is not cleared out.
