PS Panel for 737NG

Hello,I downloaded the PS Panel for the 737NG on FlightSim.com but my problem is that the switch for the red and green nav lights also turns on the strobe lights (there is no separate switch like the default FS panel). Does anyone know how to fix this problem? Also, the panel has disabled my control of the lights by using the keyboard (eg. if i type "L", the lights will not turn on/off, it must be from the panel.) Does anyone know how i can recover control of my lights using the keyboard?Thanks.
