Cann't add custom style to a region of a flexible layout.

I can change to what ever I like.
Then it looks like it works but when I save it and edit again the layout region's style are "default".
When I try to add content to a region, the "add content" menu is open I can choose a content.
But after I choose a custom content thers no change at all in the layout.

"panel page" is working great.
But I need custom layout for Views.

There are no errors at all =\
b.t.w
Im working with CTools 7.x-1.0-rc1.
is it fine?

I have an idea,
I want to import a layout with custom style.
Can someone please add some custom "Stylizer" style to this layout and post it back?

Thanks,
Amir.
