I have some 10W RGB floods that I need to have as GRB vs RGB. I've changed them in Xlights, but only one of them actually updates the channel order. I'm on a Mac running 2017.30.
I'm attaching a screenshot showing it a little better than I can describe it.
I was able to 'fix' the issue by creating virtual strings on my Falcon, but I'd rather not do it that way. The weird thing is that flood #4 updates correctly and shows as GRB. No matter what order I select in Xlights it doesn't change when I go into the testing section.
