When i open the website from mobile i am getting a small grey rectangle block above the footer, when i open the site from desktop its fine but in wpbakery page builder there is 2 columns which i am not able to remove. And when i add something to that column a background image is appearing which i removed from contact form. Please suggest me a solution.

That is default row when you edit a page via visual comport at front end.
Please view the page as normal then check again.
