Change function channel DMX UE 5.0

Hello o/

I was wondering how can I change the channel of a fixture’s function in a DMX Library (what is circled in the image). I have watched some tutorials that showed how to setup DMX but they had a setting called “channel offset”, while I don’t. What can I do?

So how can I do this?

Delete the channel and replace add fonction :slightly_smiling_face: :pray:
