Post Grid

I’m using the Post Grid plugin on this site for the pages,
https://bncr-stage.careerleaf.com/blog/, and https://bncr-stage.careerleaf.com/industry-resources/
For some reason on mobile and tablet it is showing extra padding underneath the posts and logo as well as cutting off the titles of the post.

Can you help me out?
