Slide not tracking after a particular test

I am working on a storyline file with around 150 slides (230mb). There are 8 chapters and a test at the end of every chapter. I do not know why even when I view the slides of chapter 6, 7, 8 or even if I complete the course, the scorm does track my progress completely and takes me back to take the test of chapter 5. Before, I had the same problem but with the 4th test but I was able to get it working after the creating a whole new test for it.

Every time I exit the course and then I get back, it takes me back to the test of chapter 5. Even if I complete the course, it shows "complete status" but still takes me back to the 5th test I tried the scorm on scorm cloud many times but I can't make it work.

Can anyone please advice?

Thank you!!!
