Having problem using "grid" data-columns in Wordpress with Be Theme

[arianabiz]

Hi
I have some boxes in different sizes on the home page and want to use Salvattore to arrange them.

I'm using Be Theme on Wordpress. I've entered the "grid" data-columns on Custom | ID of the section.

But when I enter
"grid" data-columns
it changes to
<div class="section mcb-section" id="" grid"="" data-columns"="" style="padding-top:0px; padding-bottom:0px; background-color:">

and when I enter
grid data-columns
it changes to
<div class="section mcb-section" id="grid data-columns" style="padding-top:0px; padding-bottom:0px; background-color:">

What can I do to use it properly?
