May be Mitras-LB-Splitter broken?

[progman]

After firmware updating from 7.28 to 7.40 I can not control my Mitras Lightbars via GHL Control Center.
There was a my mistake I connected a splitter`s socket to socket for PAB once.
Now it connected to MiLB socket of Profilux 4

Mitras lightbar & Slimline -> Profilux: usage Mitras lightbar
System->Serial = Mitras Light Bar.
Max power output = 60%

Mitras lightbar & Slimline -> PAB = disabled

But lamps light full and does not dimmable
