Hello again, @rryan ...
Thank you for confirming that you have your images uploaded to the other course and also that you've re-linked your buttons/icons to point to the correct locations in that course. The only other thing that comes to mind is something that may not even sound related to your question, but it's worth taking a look at. I would like you have both courses open at the same time so you can look at the right portion of the screen. Check out these two screenshots from my own sandbox course:


These two screenshots are from my "Modules" index page. Notice that the first one has some extra white space (which I've scribbled in purple) along the right side compared to the second image. Do either of the course pages with the same code have any extra white space on the far right side of your page? If so, there is a setting that your school's local Canvas administrator can toggle on/off called "New User Tutorial". When the "New User Tutorial" is toggled off, then there is extra white space on the right side of course content pages. When the "New User Tutorial" is toggled on, that white space is eliminated, and course content extends to the edge of your screen. So...with this information, I wonder if your other school (where your layout isn't looking like it should) does not have the "New User Tutorial" toggled on for everyone at that school? If the "New User Tutorial" is not toggled on, maybe that's a reason why your page doesn't look exactly like the first course...because the content is being scrunched slightly? This is all speculation on my part, of course, but it might be worth having a conversation with your school's Canvas administrator about what I've mentioned. There is more information on this Guide, What feature options are currently available for a... - Instructure Community (canvaslms.com), that details how the "New User Tutorial" behaves when toggled on/off. It has to do with pages being "responsive":
This feature removes the maximum width in Canvas, which affects Canvas courses. When enabled, the Dashboard course cards are responsive to the full width of the browser. Depending on a user's browser's resolution, the Dashboard course display more than three course cards in a single row. Additionally, Canvas in other feature areas such as Assignments and Discussions use the full width of the page and minimize white space in the sidebar.
Anyway...I'm not sure if this will be of help or not, but I thought I'd throw it out as something to investigate on your end. If none of this applies, then you might need to have further discussions with your school's Canvas admin or even try contacting the Canvas Help Desk staff to see if they would be able to investigate further. How do I get help with Canvas as an instructor? - Instructure Community (canvaslms.com)
Keep us posted on your progress...thanks!
