How are you determining this?
If you're using trickster, go to the last screen, and toggle off mpdecision, hit the checkmark in the upper right, wait a few seconds, then toggle mpdecision back on, and click the check mark again. This should unstick your cores. Obviously you'd need to be rooted for this, though.
