Prolights Eclipse FS - Lime not responding in Colorpicker


I have the problem, that our new Prolights Eclipe FS Fixtures behave odd when we use the colorpicker.

Its an RGBL Fixture and in 5CH RGBL - Mode, all colors responde correctly when using the color picker. But when using it in 13CH Mode (which gives 16bit res.), the Lime Color keeps unchanged at 100 an is grayed out.

So i assume, because its working in 5CH RGBL Mode, that Prolight provided samples/information to Carallon. But why is it not working in 13CH Mode?

Thanks for some help,
