Because that´s the reality …
You see, the real-world runways are 10/28 and 16/34 … in MSFS you have 02/20 (not existing any more), 11/29 (outdated runway idents) and 16/34. The MSFS suppresses now the terminal procedures, when a terminal procedure can´t be assigned to an existing runway. That´s a bug since day one of the MSFS and has nothing todo with the navdata.
We offer real-world data and you still have these terminal procedures in your data but the MSFS doesn´t shown this due this bug.
That´s also the reason, why you don´t see any terminal procedures in the stock data (means without our data). With the stock data you have only terminal procedures for 16/34 but not for 11/29 (as in the sim).
Here, all terminal procedures from the stock data:
… and here, when our data are installed:
All procedures are still included but can´t be selected due the MSFS bug. Sorry, please report this to MS/ASOBO, that the stock scenery is outdated.
Cheers,
