It is a cock-up
There is no LEDB in Spain according to ICAO doc 7910. The only two ICAO's in that series are LEDF (Madrid Air Defence Co-ordination Centre) & LEDM (Valladolid COM/MET centre).
The airfiield at Ledbury doesn't have an ICAO designator - obviously the person who has written this website has shortend the name to its first 4 letters, thus causing the confusion).
