Editing Custom Code for side-by-side blocks

Site URL: https://ifstherapyonline.com/rates-insurance

Hi there!

I am editing a website developed by someone else, and can't seem to make sense of the code they used to make certain aspects of the site. For example, I am trying to update the text on the "rates" section, however, I am only able to edit the text once there is a mobile break (aka once the blocks stack), and the changes do not show up when viewing in desktop mode. These changes are also able to be witnessed on the site & I've attached images of the back-end here. The third image is what it looks like when I try to edit in full screen. 

I suspect this may have something to do with the height of the blocks, but I've tried isolating the code that I think relates to this, temporarily removing it, and still the same problem exists.

Is it recommended to remove all of the code injection in order to fix this issue before reapplying, or will that mess with the rest of the website? 

Don't quite understand the problem. Can you add a quick video when you edit text?

Here's a loom video I took of me explaining the issue & a video view of the custom code already in the site: https://www.loom.com/share/24958b538a1c439faed22f0d7502d4e9
