How to update projection of NavigationTestingActor?

[foggedfrog1 (foggedfrog)]

In Unreal Editor 5.4, when moving NavigationTestingActor programmatically (with Python) or by scrubbing the coordinate inputs, its projection (green sphere) is not updated and is stuck at its previous position.
Could any parameter be changed, or could some function be called to solve this?

The Python function I use to move the actor in Python is:

nav_actor.add_actor_local_offset(v, False, False)

I solved this without using NavigationTestingActor but instead by calling ProjectPointToNavigation in the NavigationSystemV1 directly.
