"Next" Buttons Triggering Clicks

Hello! 

I'm hoping someone with a bit more experience can help me with a button/trigger issue I'm having. I'm creating a course that has some slides that go into a software simulation activity in Storyline 360. In the course we have custom navigation "buttons" (shapes with triggers) that allow the user to navigate to the previous, next, home, and help slides. They work all throughout the course as expected; however, when I use the next button (the object not the one in the player) on the slide before the software simulation starts it triggers a click on the first slide of the simulation triggering the wrong answer layer. I can't figure out how to stop it from registering click that doesn't occur when using the button. Help?  

Here's the "button" we created as well as the trigger: 

      

And here's how what it does when the button is clicked: 

I'm sure it's just a case of the trigger not being set correctly for this transition, since it works as expected everywhere else. If it helps, when the next button in the player itself is used this doesn't occur. 

Thanks for any help you can give!
