Inaccurate Quiz Result

I'm using Captivate 2018. The quiz is branch aware (2 quizzes for 2 locations).

My problem is that one quiz reports just fine, but the other only allows a user to achieve a grade of 96% even if they answer all 25 questions correctly. The problem is not with the LMS; it also occurs when I do a project preview in Captivate.

The final score slide tells me...

You scored: 24

Accuracy: 96%

Maximum Score: 25

Correct Questions: 25

Total Questions: 25

I've done some troubleshooting already and have ruled out the following:

• There are no extra buttons anywhere in the project with the "include in quiz" setting enabled.
• All questions are weighted properly with no penalties assigned.
• The "Report Answers" box is checked on all necessary questions.
• All question types are set to "Graded".
• I've looked over the question slides that are specific to the quiz branch that's giving me the issue and all quiz slide and submit button properties seem to be normal.
• I've gone through a review after passing the quiz to see if anything is being marked improperly and everything looks fine.

This test was copied and updated from last year's training, so very little has changed about it... I'm not sure if duplication perhaps is causing an issue?

I'm baffled. Has anyone else ever run into this type of issue?

Thanks,

Steve
