The automatically generated world map plan has decided that your approach is to be flown with no transition, and has not sent a transition with the plan. This results in the following plan:
As you can see, no transition in the Garmin units is the same as selecting VECTORS, which is a VTF approach. The plan is in and shown, as you can see on the map, but there is a discontinuity between LIRP and the start of the approach, because it is a VTF. This is the correct depiction of this approach selection, according to what the world map sent.
If you would like to fly this approach with a transition, you can always add one on the PROC page. The sim does not always select one for you.
