Hello @Boris
This is still an issue in the latest SU3 Beta and I was wondering whether this would still make Su3 or if at least SU4
I reported this in November and it is still an issue 8 months later… 
At first I didn’t know that this also affected custom native 2024 lightrows. I thought it was a backwards comp issue and only default items where affected. However, now that we are trying to start working with 2024 and doing native projects, I was quite puzzled to find out that not even fully custom lightrows work, although they work prefectly fine in the 2024 editor. Quite frustrating to be honest. I can live with default PAPIs not showing up as a backwards comp issue. But not having taxiway lights is quite an issue and not of high priority as this threads states but, in our opinion, a severe blocker…
Any update would be appreciated 
Best,
Michael
