Next Button not progressing when users clicks

I am relatively new to Articulate and discovered last week that I could set triggers to disable the next button until audio on a slide completes then set it back to normal. When I tested it, I thought it worked to then click on the next button and progress to the next slide.

Today, however, I'm seeing it does nothing. I have the following triggers set up in order:

1. Change the state of next button to disabled when timeline starts. (works)

2. Change the state of next button to normal when media - audio 1- completes. (works)

3. Jump to next slide when user clicks next button. (Does not work)

What am I missing? I've attached screenshots as well.
