Hello there, @Justin_Cole ...
By chance, does your Canvas screen look something like this...where the menu items normally displayed within the green box (shown below) are not appearing for you?

If so, this is a super easy fix. At the top left corner of your screen (just to the left of the word "Pandora" in my screenshot"), you'll see a three-lined menu (hamburger) icon. Click on that icon, and the course navigation menu items will re-appear for you.
I hope this will be of some help to you. Please let Community members know if you have any other questions about this. Or, if I've not interpreted your question correctly, please provide additional details so that we can continue to help troubleshoot with you. Thanks!
