Thank you, the reason is XP11 and not the navdata …
The default XP scenery has two wrong runways included which can´t be assigned 16/34 instead of 16L/34R. Thats the root cause of the issue. The flightplan is correct so far, and the navdata inside XP11 are also correct for RKSI.
Here the wrong data from the XP APT.DAT file (this file will be supported by LR and is not a part of our updates):
You also see that in the log.txt file:
0:02:55.689 E/SYS: +-------------------------------------------------------------------------------
0:02:55.689 E/SYS: | Procedures could not be loaded:

0:02:55.689 E/SYS: | (async_proc_loader.h:50)
0:02:55.689 E/SYS: +-------------------------------------------------------------------------------
In other words, please report this to LR that they can fix this. It´s not a navdata issue, because the runways are existing, but not 16/34 … this runway doesn´t exist and therefore the procedure can´t be loaded correctly.
Hope that helps,
Richard
