Attack Animation Not Working [1.12.2]

Hi, so I'm having some problems when trying to implement an attack animation for my entity. I've even went through the IrongGolem's entity and model class to try and find answers ending up using a portion of that exact code on mine but, unfortunatly, it doesn't seem to work either. The problem that I'm having is not that the entity isn't animating when attacking, the problem is that all the entities animate in sync when one does. Basicly when one instance of my entity attacks all the the entities play the attack animation at the same time. Please help, I've looked through every tutorial and forum I could find but I still can't find any answers to my problem. Any sugestion helps. Thanks you for your time

Entity Code:

        ambientSounds.add(SoundsHandler.ENTITY_TREX_AMBIENT1);
        ambientSounds.add(SoundsHandler.ENTITY_TREX_AMBIENT2);
        ambientSounds.add(SoundsHandler.ENTITY_TREX_AMBIENT3);
