Spline custom details panel not working in actor editor

Hello,
This only happens in the actor editor viewport.

I have this issue where when I modify a spline point location via the details panel, the spline point doesn’t actually move. However, the property actually get modified and if I close and reopen the actor editor, the spline point is at the new position.

Note that this doesn’t happen on UE4

This kinda bother me, because when I implement my own custom detail panel in a similar fashion of FSplineComponentDetails I get the same issue. The property get modified but the change is not updated in the viewport

Is that a known problem ?
Anyone have the some issue ?
