Hi Daniel,
first of all, thanks for transfering your report into the correct category and also, no need to apologies you. All is good - but it´s easier for us and also for other user here, when they can expect a clear answer of a clear question 
To BAGSO2L at Dublin:
This is a logic bug in the sim. Try the same in the worldmap - select first only the BAG2L STAR and you will see this:
Which looks correct so far for the STAR. So, all waypoints are in the correct sequence. Now add the approach ILS28L to this STAR and you will see this:
So, you see there is a long term logic issue here, when ASOBO connects STARs with approaches. It doesn´t happened only here - this is a general bug in the sim. Also, it also happened all aircraft which are equipped with any FMS/Cs, Garmins, … therefore my assumption, that this is a general bug in the underlying engine.
You see how it could be work in the Working Title CJ4
This mod reads all data correctly and the result is a perfect STAR with an perfect approach part:
Sorry, I guess you must wait till ASOBO has fixed their engine or the FBW guys have also fixed this.
Cheers,
Richard
