Wolfmix

I have a strange problem. I have no fixture in Universe 2. But when i try to add a fixture to universe 2, the first free channel is 57. When i look at the dmx value page i can see some strange value in the dmx table 1-56. I think i have done something in the beginning when i first boughted the Wolfmix and added a fixture to universe 2 but than deleted it.
How can i clean the Universe 2 so all channels will be available?

check if you have a Live Edit assigned to those addresses. This will still block the addresses, even when the fixtures are deleted. Make sure to COMPLETELY delete the Live Edits. Go to Live Edit. Press SHIFT+[slightly yellow glowing) Live Edit Preset. Dial rotary encoder from SELECTED to ALL. Push encoder. Now delete name.

Thanks for the answer. Yes that's the problem. I had some live edits with some static value in some dmx channels that I don't used anymore. Problem solved.
