Cannot edit grid panel

Howdy,
I’m trying to do something really simple. If you go to my about->team, I want to add more panels to the photo grid that shows under the big group picture. It shows three of my team members. I am trying to add three more rows for 7 more people. I cannot for the life of me edit this. I am using a Sensible Child theme and I am using wp-stage. My PHP version is 5.7. I can’t see where to edit this in style.css. Elementor will not touch it. I am trying to roll this site out tomorrow and this is the only thing holding me up.I think whoever originally made the website used a since-broken plugin to create that field. I tried every theme editor I got to no avail. Help!
