@Sakin: Checking the forum I found someone with similar problem with different template:
http://catchthemes.com/support-forum/topic/layout-option-previews-but-doesnt-save/
I had a test:
1) Change layout from dropdown menu
2) Click on Show preview (I usually don’t use it 😀 )
3) Save
In this case the layout is saved even for pages that it wasn’t working.
Now that I know it I will do it 😛
Hope it helps to fix the problem 🙂
