Strange Queue Tree behaviour in WinBox

I have a Queue Tree with one parent and two children as in picture. Problem is when I change something in queue toVCS or just simply click “Enable” on it queue toOtherLAN stops working. If after that I click Enable on queue toOtherLAN it starts working again. What am I doing wrong?
