Please help me connect the Unreal Engine to DOT2.

Hello, I am a student studying DMX in Korea. The connection between Unreal engine and dot2 was successful. But the lights connected to Universe 1 moved, but the lights connected to Universe 2 didn't move. I would appreciate it if someone could help me.

Thank you. I thought it was a problem with my settings, but I can only use one Universe on PC.
