Firewall thinks .exe is in different folder to it's actual location

When I run D:\Games\ArmA 2 Operation Arrowhead\Expansion\beta\arma2oa.exe despite having rules allowing that through the firewall, I’m getting popups and clicking on the filename on those reveals that the firewall thinks I’m running D:\Games\ArmA 2 Operation Arrowhead\Expansion\beta 94700\arma2oa.exe

That folder did exist until I renamed it just \beta\ but I never ran the exe from it whilst it was named \beta 94700\ and even if I did, that folder doesn’t exist now and I’m not running the .exe from it, so why does the firewall treat it as if I am?
