Storyline 360: Next Button State is Normal at Beginning of Timeline

Storyline 360 Build 3.102.35072.0.

I've seen similar posts on setting triggers for the NEXT button, but I can't seem to find one that quite matches my issue. I am having an issue with the NEXT button appearing in its NORMAL state when the timeline starts when previewing the slides. No triggers are set.

I previously have only been updating existing projects that other designers have created. I have been tasked recently to create a project from "scratch." When I create and preview the new project, the NEXT button appears in it's NORMAL state at the beginning of the timeline. To have the NEXT button function as intended, I have been using triggers to disable the NEXT button when the timeline starts and enable when the timeline ends.

I was advised by a fellow designer on some feedback on a new project that I did not have to set triggers timeline starts and enable when the timeline ends. From all online Storyline support and user information, the NEXT button SHOULD NOT APPEAR until the timeline ends by default. The other designer on my team does not have the same issue and does not need to set any triggers to affect the state of the NEXT button.

I am thinking 2 things:

1. There is a global Storyline property setting that I may have set without realizing it.
2. There is an application conflict with a different application that is affecting the state of the NEXT button to disregard the objects and timeline duration created on the slides.

I have attached the following: 

• Storyline 360 Timeline Issue.story (a non-proprietary sample)
• Storyline 360 Timeline Issue Timeline Screen Shot.jpg
• Storyline 360 Timeline Issue Preview Screen Shot_Slide 1.jpg (Note: In the screen shot, the player is still in the middle of playing the objects on the timeline.)
• Storyline 360 Timeline Issue Preview Screen Shot_Slide 2.jpg (Note: In the screen shot, the player is still in the middle of playing the objects on the timeline.)

Any insights on how I can resolve or helpful information to assist in determining if there is an application conflict that is causing this to occur.
