Last DALI device not working

[managementboy]

Sorry, maybe I did not explain my problem correctly. I have two Lunatone Dali dimmers. Each has 4 devices. They show up as 0-3 on one Lunatone and 4-7 on the second. The 7th output does not react to any command. But it is detected. See this screenshot:

   

If I attach the stripe I had on a different channel I get perfect dimming and commands. I feel like there is a bug somewhere
