Widget child not updated after compilation

I’ll try to be more precise.

I have a first Blueprint A Widget that integrates a progress bar and an IA_jump input action that should define the percentage of the progress bar when triggered.

I have a second Blueprint Widget B which integrates a canvas and my Blueprint Widget A.

When I add my Blueprint Widget A to B and run the game, everything works. The IA_jump is triggered.

Now I’d like to change the color of the progress bar in my Blueprint Widget A. I change it and recompile the Blueprint A Widget. I launch the game and the IA_jump no longer works.

I hope this is clearer.

About the Canvas Panel, is attaching through my Widget Blueprint B in a player controller.

Anyway, thanks for taking the time to reply.
