You applied for a settlement visa whilst simultaneously holding a valid family visit visa. Your settlement application was refused. You want to know if they can cancel the family visit visa because of this.
Yes, they can cancel any visa any time they want. In your case they did not cancel the visit visa when they refused your settlement application, so it remains valid. When you next present your passport at a UK entry port, the Immigration Officer has the option to cancel or not. He will generally cancel an entry clearance ONLY if it was obtained by fraud or a change in circumstances has occurred; so you should be prepared for a line of questioning on these topics.
