Hi Azza - We have noticed that problem if you have copied UHD source / sinks from another flowgraph into the one you are using. Try deleting the UHD blocks and re-creating them in your flowgraph and see if that fixes the problem.
There is some bug in copying those blocks between flowgraphs in GRC, I think.
