Head movement animation

Hello, I'm making my first mod just for fun and without knowing anything about programming. And I'm having problems with the animation of my mob's head


The problem is, when the "head movement animation" box is checked, the head simply does not work correctly in other animations, such as idle for example.

What could I be doing wrong?

Remembering that I modeled and animated it on Blockbench and I'm using the geckolib plugin.

In the image, the penguin's head was supposed to be under the right wing, but it simply turns to the left on the X axis
