It is really hard to understand the workflow you have stated above.
Could you please package your project and share it with me using drop box. (email@example.com)
Also please mail me the detailed steps and expected behavior for different slide numbers in order to understand the issue better.
Note: You can package your project using the Package option available on Presenter ribbon.

I just emailed you on it.
Analyzed your project file.
It seems like you are trying to skip a quiz question using Advanced Answer options, while in your quiz settings "Answer All questions" type is set. This is resulting into a conflict while you are trying to skip one of the question slides.
My advice would be to change the quiz settings to a different option like "Pass Required" with Pass/Fail Options set to 0% (Since all questions are survey type in your case within the Evaluation quiz) or "Optional Quiz".
Please mark this answer as correct if you find it helpful.
