When I change the color of the icon in a variant of a button in the main component, this change only affects instances of the same variant that have the same icon, but not those with a different icon.

Hello. Does anyone know why, when I change the color of the icon in a variant of a button in the main component, this change only affects instances of the same variant that have the same icon, but not those with a different icon? I've tried several methods, but this issue keeps happening. Am I the only one experiencing this, or has it happened to someone else? Does anyone know of another way (other than switching the variant of the instance) to solve this?
