Some of the products from our "Free" category are free additions to our paid products. Those free products do not work without the plugin which is why our store automatically adds it to your cart.

If you already own the paid product that is required by the free addition to work, then most likely it is being added to your cart because you are not logged in onto your MotionVFX account at our website - please login onto your account before putting the addition in your cart.
