How to turn off Cascade Nav Bar?

Question

The nav bar (on the left if that is what it is called) displays as a cascading nav bar, making it difficult to navigate. This only happens on one of my two computers, it happens in Chrome and MS Edge.
I've tried deleting my cookies and registry keys but nothing helps

@Matthew Morris I vaguely recall a similar post (in the last 19 months), but I'm apparently not putting in the correct words to search for it. 🙃 You might try searching in the Questions area.

In another post I found (https://community.atlassian.com/t5/Confluence-questions/How-to-change-width-of-the-Space-Content-Tree-on-the-left-side/qaq-p/2394282), there was a suggestion to check Console errors in your browser. As I've never opened the console for my browser, I cannot know what you might look for there.

they are nearly identical in hardware and software, including screen resolution. Same OS and same browser. I've tried ME Edge and Chrom, I've deleted cookies and registry keys... no change. It's odd, my coworkers do not have the same issue looking at the same page.
There are a few pages where I can go too and it will properly align the pages vertically, this is mostly a hail-marry attempt at fixing something that has bothered me for over a year

No worries, Matthew. I'm wondering if there's something different with the two PCs and their setup.   Are you using the same OS, same browser, and the same browser version?  Is the resolution on the monitor the same?  I know weird things happen with the zoom level on the display or browser is bigger than 100%, is that the same for windows as well as the browser? If you change the resolution of the monitor, does that make a difference?  What happens if other users login on your PC, do they experience the same behavior?  Have you tried flushing your browser cache & cookies? Just trying to eliminate some possible causes.

Hope that helps.
