Slides not appearing in menu

I have asked this question before but still can't figure it out. I have a question slide, they pick their answer and it advances them to the next slide. After that slide, about 10 slides won't show in the menu, despite my resetting the player menu many times. Each icon has a trigger when clicked and there is a previous and next button, that's it. You can see 1.5 - 1.12 won't show.  Thank you!
