Moving points & regeneration on spawned spline PCG in editor (UE 5.4.1)

Hi,
I spawn a BP with a PCG through an editor utility widget on my scene in the editor, not at runtime.
I have a small custom event in the BP that I fire right after spawning to force the regeneration of the PCG in order to make meshes appear.

Despite this, when the spline is spawned, if I move points, the PCG doesn’t update unless I move it with the gizmo or hit “force regen” manually in the PCG graph. The issue does not occur when the BP is drag from the Content browser.
Does anybody know why and if there’s a workaround ?
I’m on UE 5.4.1.

When dragging it from the Content browser:

I am facing similar problem. Have you found any workaround?

hey,
it was a bug with UE 5.4.1, with the most recent updates the problem was solved
