172 sp

I am trying to put together a set for the default 172sp GA.  I have even copied a tubeliner and placed in the custom folder and renamed the file correctly for the 172 as shown in the videos.  but when I pull the plane up on the runway and select for the equipment to be there, I can see nothing.  No waypoints, no limos, buses, etc.  If I pull up the 737-400 and do the same, everything shows up there.  So what could I be doing wrong?
