Trigger changes wrong button.

I am finally done with my biggest attempt yet using Storyline and everything seems to be working EXCEPT one of my triggers will not work. On Slide 14.1 there is an Example 1 Button. When you click on it, it takes you through a series of screens 2.1-2.10 and when you get to the last one (2.10) there is a trigger there to make CompleteScene2 = True. Then when you return to 14.1, the Example 1 button should have changed over to the "Completed" state. However, it always changes Example Button 2 to completed. If I do Example Button 2 first it changes correctly, but then Example 1 button still won't work. I can't find the error despite looking for 2 hours. I'm sure I'm missing something small. Any help?
