Trying to change the offset of a material in an animation changes the offset of the other materials

I dont know if the title really explein what I am having problems with.
So I am trying to make an animation for a cutsene for this character I made that has 3 different materials

I can move the offset without problems and the corresponding texture changes in the model


But if I try to change the offset of the material while doing an animation the offset of the 3 materials change

Does anyone know why this happen, and if there is any way to solve this problem?
