Contax/Yashica with EF adapter on Speedbooster?

I just bought 2 C/Y lenses for my BMMCC, and after trying them out, they don't seem compatible with the Speedbooster (Pocket). They do connect properly, but the aperture blades stay totally open and they don't close. Has anyone had this same problem? Any workarounds?
