I've had this problem with EGLL, I had the Orbx London landmarks installed, the only way I got around it was to uninstall the Asobo discovery London file, as the Orbx one is better anyway.
I've had these pedals for6 or 7 years and use them most days they worked well with FSX and are working just as well for msfs they're easy to set up and comfortable to use I wouldn,t hesitate to reccomend them to anyone
