Awards come from a different ‘inventory’ than cash tickets. It is very well possible that award space has either not (yet) been made available or has already been depleted on the flights you are looking at. Especially F award availability from LHR is very difficult to find as that is a very ‘F heavy’ route. It can be very frustrating.
