g8 male (g8.1 too) eyes and mouth interior not following morphs

ZW

Hi I recently purchased this morph product https://www.daz3d.com/genesis-8-male-head-morph-resource-kit-2

I like the product, but the problem is that the eyes and the mouth interior don't follow the morphing (So if I create a morph with eye distance to give an example, the eye balls stay in place while the face stretches the distance of the eye sockets and therefore leaves empty spaces. The same is true for the mouth interior.). Basically the morphs on the outisde work, but the insides are not affected, they don't follow. It's the very first time I get this problem with a morph package. Anyone knows what could be the cause of this?

Thanks!
