Joysticks N sliders question with multiples comps

[PS Motion]

Hello! I have a rigged character that is setup like this:
- There is a primary comp in which you add your art to each body part and then adjust the spacing and position with some sliders;

- There are multiple precomps with preset animations that automatically get updated with the art I added to this primary comp above;

- When creating the head, I used a precomp, instead of a flat layer, so that I could rig the head, eyes, mouth, etc using Joysticks and Sliders.

- In my Main comp, I use the premade animation compositions in the order I want and I pushed the controls of the Head rig to this comp.

However, when I started animating the head, i noticed a problem. If I add, for example, a blink animation at 1s in the Main comp, I noticed that a blink happens at 1 second in every other premade animation. Everything I animate at the main comp gets replicated in all the other comps that have the head. I thought the controllers would affect only the Main comp, since i've pushed them there. 

What am I missing here? How can I animate the head and face only in the main comp, and not in every comp that uses the Head?

Thanks for the question, @PS Motion. My name is Kevin from Support, and I'm a moderator here. While we await an answer from our community, is it possible to share the file with us? If it needs to remain private, you can PM me, and I'll pass it along to the team. It sounds like you may want to create a more simple version of the comp to see if you can find a better workflow. Many people are using DUIK or Character Animator for some of this work. That may be another idea for you to try while we await a response. I hope we can help you shortly.

Take Care,
Kevin
