Oh, thanks Andreas for this reminder … sorry …
Yes, we had received an answer - it´s a confirmed limitation. Asobo knows this and as they told us, that´s currently their logic in the flightmanagement. Means, all in-game aircrafts or the WorldMap use these flightmanagement in the background. So, they are aware of it but that has nothing todo with the data-provider in the background, it´s independently of the data provider - it´s their current logic.
We have opened a new category called “Known issues”, where we post all known sim limitations/issues, which can´t be fixed by us and also which is data independent.
Here the posting about the STAR/Approach logic on another example:
Sorry for this not so good news, but I´m pretty sure, ASOBO will fix this in the future, they are aware of it …
Cheers,
Richard
PS: I close this now - I hope it´s ok for you 
… but we can´t do more at the moment.
