Horizontal Repeating Group Responsive Design

Hi everyone,

I’ve recently come to a problem regarding horizontal repeating groups. I am using a horizontal repeating group to do paginations on items. What’s happening is in my editor I’ll say the repeating group to have 4 columns but in my preview it shows only 3 columns. I haven’t run into this problem before so any advice would be greatly appreciated. I’ve attached pictures below.

Thanks!
