Bug Mini game not transitioning to the next question

I'm trying to add a mini game to a zombie in my game. The idea is that when I kill it, a true/false mini game UI should appear first and transition to the next questions until the player answers 3 questions correctly, once they do, the Body Item Collection UI should enable, if they don't neither should enable. However, as it stands, the transition to the next question does not occur. Please refer to the 2 min long video I have attached to get a better understanding. I should mention that I took this mini quiz game project off of github, in it, there is a "Material UI" asset being used, tho I don't think that is the cause of the issue.
