Showcase and Sleekphoto child themes

Hi,

Okay this is a silly issue. I added the Showcase and Sleekphoto to my host including their child themes. But I can only see the Parent themes in the Network Theme Activation and not the Child themes. This doesnt happen with Studio and Nelo themes. I dunno what I am missing here.

I checked clearly using shell whether the child directories are there and I see they are.
