Hi, just send the desing to you. The problem reveals, when I toogle on any of the hidden groups. Probably its because of cyrrilic group names. On the same mock, but with latin group names, everything works just fine.
@xamedow seems odd that latin characters fix it.
I would say that if you get a PSD where all the groups are displayed then it works - you would still be able to hide groups you don't want to be displayed.
We will fix this in the next release.
