First of all welcome here at Navigraph. Please use the search feature here in the forum. This feature is working very well and you find the answer in one of the latest answers.
In general, the default KORD scenery in the sim hasn’t all runways available. The logic in the sim is now: when an arrival route can’t be assigned to a runway, they suppress all STARs.
But that has nothing todo with the data because all STARs are still included but the sim doesn’t shown these due this limitation. Sorry
