Aligning Elements with Relume Figma Kit: Column Configuration Guide

Hey, I’m starting a project using the Relume Figma kit. When I turn on ‘Columns’ to help align elements I can't seem to align them. The desktop breakpoint Frame is 1440px and looks like the Margins are 64px. When I set 12 columns with 20px Gutter and ‘Stretch’ the Relume elements are not accurate to the column widths? What am I missing here? Is it something to do with out-layout configure or the Webflow REM conversion? How should I configure the ‘columns’ to get it work with the components please?
