the top parts are still full of AIR repeat the bleed process again ignore the water that is coming out,( a rag helps soak it up) it will change to a hissing sound when hissing stops and water appears again close the bleed valve, the whole of the rad panel TOP should now start becoming HOT. repeat procedure at the other radiator.

note
if combi the system may need a top up water via the filling loop
