Interesting, for FTX PNW you want to disable or remove three files for CYVR ADE_FTX_PNW_CYVR_Vancouver_Intl.BGL, ADE_FTX_PNW_CYVR_Vancouver_Intl_CVX.bgl and FTX_PNW_objects_CYVR_PLC.bgl. But if you have already done that then it could be some other file that you have added.
Maybe take a screen shot of your traffic parking at YVR so we can see, that might give us some idea.
