After Paper-Dialog Displayed, Paper-Button Throws Error on-tap

[caseybaggz]

I have this weird issue that I'm not too sure why it is happening. I have a paper-dialog that allows me to submit a form. Once the dialog has disappeared and I want to click another button to do something, the button fails and the console logs this: Uncaught TypeError: undefined is not a function hero-transition.html

Not too sure why? I have no hero-transition on the button? Here is the button code:

<paper-button on-tap="{{startMatch}}">NEW MATCH</paper-button>

It only throws that error when I open and close a paper-dialog. Anytime other than that, it works fine?
