Bug: playback bars not showing up properly on screen

Hello,

I think I have a bug with a full boar 4 (3.6.1) in combination with a master wing.
I have playback bar 2, 3 and 4 assigned to the master wing,top to bottom, and have them on the screen. However, when I start my show the on screen playbacks are in the order 3, 2, 4. I then drag and drop to get them te right way around, but it's very annoying to have to change it every time.
I attached a picture of the situation when I boot up.


I also have a fader wing (with screen) attached to the desk, which has playback bar 1
