SiteOrigin Page Builder with Sahifa – Huge empty space

Hello everyone,
I’ve just installed Sahifa Theme, and I’m using SiteOrigin page builder for my posts.
Posts with SiteOrigin used leaves a huge empty space at the top of the post
example: http://mygust.com/math-130-basic-calculus-reviews-previous-tests/
Posts without SiteOrigin looks fine

أي قائمة تشوفها الأنسب, وصوتك لها؟ 2016-2017

Can you please help me with a fix?

Thanks.
