That actually sounds entirely normal. New players always have this sort of unwanted muting problem. You are doing fine, try not to let it get you frustrated. Even though you pick things up quickly your fingers may not :)

I didn't see you specifically say you are using the core learning system. We designed that system to teach you things like this that come up in the beginning. I would recommend it.
