It´s the same - check the runways against the real-world charts. When a terminal procedure can´t be assigned to a runway, the sim disable all STARs. That´s a sim logic and has nothing todo with us or our data. The LEBL example is a good one, because here you see that the stock navdata data shows also no STARs …
Sorry, you have only two possibilities:
- wait till ASOBO/MS fix this (mean offer the correct/real world runway idents or add missing runways)
- or use any 3rd party addon scenery
Also for KORD are a lot of postings here in the forum (as an example):
