Your first 3 sections are visible on Desktop but hidden on mobile. The 4th Section is the one that you're seeing on mobile, that is the section that you need to edit.
It's weird that you're using PRO but the demo you have (integrity 1) is for X, maybe this is an incompatibility issue. And I see that you're still using PRO version 1.1.1 which is kind of outdated, the latest version is PRO v1.2.7. As you can see in my video clip above the Cornerstone interface is different.
If your schedule allows, I advise updating your PRO to the latest version.
