LED Bar Channels won't switch off

[fas]

Hi everybody,

I'm a complete newbie, but couldn't find an answer in the docs, so sorry, if my following problem is quite obvious for you.

I'm running QLC+ 4.12.6 on MacOS 12.6 with Apple Silicon.

I have a couple of Stairville 24ch LED Bars, with 8 segments, so the first 3 channels control the RGB values of the first segment etc.
I set up 3 channel groups for all red, green, and blue segments.
Now, I have a simple Scene "Red", for example. It uses all channel groups, with red on 100 %, and green and blue on 0 %. Easy enough.
Looking at the single channels in the scene editor's "All fixtures" tab, this looks as expected.

I control the scene with a simple button on the virtual console.
However, as soon as I switch to operate mode and turn on the scene, while the red channels are correctly set to 255, the green and blue channel are not at 0 but at 36 and 48.
So, I never manage to get a "pure" color.
And this problem holds true for all other functions (RGBMatrix, Chasers), I tried so far. So channels that are supposed to be at 0 are on some sort of "base level", and I don't know where this could have been set.

I did not change anything regarding the channel properties. All are set to HTP, with no modifier set.

Any help would be highly appreciated!

Please attach your .qxw file here.

I'm so sorry for the late response, @janosvitok.
As I continued working on the .qxw file, I'm afraid, I can't provide the faulty version anymore. I was able to fix the issue eventually by removing and re-adding the fixtures. Unfortunately, I can't tell for future readers (or my future self) what the problem was, but removing and newly adding the fixtures solved it.
