Problem Blueprint Energy Progressbar

im curently working on a small personnal project
Small game in a cavern body, the character is equipped with an head-lamp

The energy of the lamp is gradually declining from 100%. At 90%, the intensity of the spotlight is declining, at 30%, its starting to flicker and at 0 it turn off

But, when the player enter a trigger zone and press a button (R) and keep pressing it, the energy should be recharging.

Now i linked it to the way the documentation explain to make a simple HUD with a progress bar and it partially work. The progress bar is declining correctly and the right timing, but it is NOT recharging, while the log clearly show that the energy HAS augmented.

Here are the blueprint from the FirstPersonCharacter that i added
