According to Airac 2313; for P2ATC -> Taxi Mnt -> search for airport ICAO code -> Save/Load tab -> Load Airport Taxiways (choose the xxxx_Taxiways.gxl file from the download [replace xxxx with the ICAO code of the airport]) & Load Airport Gates (choose the xxxx_Gates.gxl file from the download)
Only runway 04R/22L is being used in real life (except for runway closures), so you should uncheck the other runway in P2ATC runway tab
