How to remove border from heading section

I Just got starting with Qubely Pro, very first thing I did was to import a section, Heading 9, and added a bottom shape divider with a white background color.

But there is a thin border around the section that I must remove (see link image), but I do not see how to do that. Under background there are border-settings, but the border width is set to 0, when I play with border style, color and width, it seems that there is another kind of border… Maybe somebody here knows how to do that?

Thanks!
