widget width in Full Width layout using page builder

Hi
I am currently using Sydney Theme with page builder

I’m facing the same problem when I use siteorigin slider widget (or any similar slider like Meta slider) inside full width stretched row
one resizing the window to arround 780 px width, some things aren’t working right for me.
it show unwanted padding on the right and left making the slider not full width on mobile devices.

P.S: I tested on Vantage theme on local machine and working well, it seems compatibility issues with sydney theme.

Any help would be greatly appreciated
