Questions blocked when retrying Quiz

Hey guys,

I'm having some strange issues with a project and can't seem to diagnose the problem. I originally created a module with a Pre-Assessment and Final Assessment. The Final has multiple attempts so the user can go back and retry the questions. This all works fine, however, I needed to create a new version of this project that doesn't use the Pre-Assessment, so I deleted it and retargeted everything to navigate correctly. When testing this new version, when I try the Final Assessment once, its fine, but when I retry it, the question are blocked and I can't click them.

I added the Pre-Assessment back in and simply navigated around it, and the questions worked fine. So something in the Pre-Assessment is affecting the Final, but they are not connected by any variables, they are drawn from different Question banks, and are not otherwise connected.

I can leave the Pre-Assessment in there, and navigate around it, but I need a way to remove it completely without breaking the rest of my project.

Unfortunately I can't upload the files as it is a client project, but please let me know if you need any more information. There must be some function that I'm not aware of that is linking the Question banks or something, so if anyone can think of something I might be missing here I would really appreciate some advice on this issue.
