…Are you sure the second set got really imported and the engine not simply replaced them with an own version?

Hi , thanks for the reply. Yes, I’m 100% sure its using my own layout because it shows when I toggle the uvs for channel 1. Also; in Lod0 - generate lightmap UVs is disabled, Source Lightmap Index is set to 1.
Edit: I did some more tests and my guess is: Unreal is creating new lightmap uvs instead. Submitted the bug.
Edit2: added an image for clarification
