Geckolib's "stop current animation" procedure block doesn't work

The "stop current animation" procedure block doesn't work, the current animation still finishes before starting the animation called "phase2":

I'm using MCreator 2023.2 with Geckolib 4.8.7 (by the way, in Manage Plugins, the geckolib plugin has "fully loaded" set on "no", idk why)

I tried updating MCreator and using a 1.19.2 generator to be on the latest version but it didn't work.
