Hi!
I tried two method to clone my section design, but not working either.
I originally made a section design with two shape dividers.
I tried to make a global class, but when I added this class to other section, the shape divider are gone.
After I tried simply (without global class) copy style - paste style method. Everything are cloned but the shape divider design is gone.
I used the built in shape in editor (tilt for section top and bottom too).
