Next or Previous Button does not work on all slides
Using Storyline 2, some of the slides in Preview and Publish (same in slides fail in either scenario) have the Next or Previous button not working.
I have checked the Triggers for Next and Previous buttons, copied the triggers from a slide that both buttons work. Checked the Slide Properties.
Slide Advances "by user" for all slides.
When Revisiting "rest to initial state"
Slide navigation controls: Previous and Next checked
Player features "Player defaults".
