Multiple Quiz Result Pages not tracking score correctly.

In the attached file, there are 4 quizzes with respective result pages. However, when I publish the file and upload to test, they are not tracking correctly. Some quizzes show a score of 80/80 even though all questions were answered correctly. While some result pages show a loading screen. I have checked the use count and made sure they align with the question banks. Is it not possible to have all four quizzes in one file?
