Issues with column display on mobile branding file

Summary

Issue with job descriptions and job lists appearing in a column to the left of the screen

Wondering if there is a way to amend the column amount or appearance for mobile career section? We have been trying to implement a new mobile branding file but it seems the job description and list are pinned to the left hand side? Is there a setting to fix this? Or does it need to be done in the branding file? If so what needs to be added into the file to fix?
