vB4 additional.css showing up on the wrong theme
 

So I'm creating a theme...a child theme of vB 4 Default Style...and I'm making a bunch of changes on additional.css.

For some reason now, when I go back and view the Default style, it's pulling the additional.css file for the child theme that I created. If I view the additional.css for the Default Style, nothing is in there.

what's going on with this?
