Hello, I was wondering if I could get some help. I have two vector images that I can select individually (see each attached picture) but when I try to combine them the button to do that is no usable. Even if I add a new shape directly in XCS it still does not want to combine/subtract with my image. For some reason it does with the upper image but not the lower image. Nothing is grouped together either. What could be the issue with the lower image? 

Thank You
