Well my suggestion is as follows. Isolate all other radiators in house, turn pump to maximum speed and see if it fills completely. Failing that close both rad valves and undo rear bleed valve using a cloth to mop up the water that will come out, though should soon lose pressure. Then open front bleed valve fully and poke a needle in it, if no different remove bleed valve assembly in total and have a look at it.
If it appears okay open one rad valve gently and see if it fills completely.
