Hover state not working on simple continue icon, but does work on my close icon.

Hi!

I have tried several things, but can't figure out why the hover state on my continue button doesn't work but the close icon I made does. I started with the close icon, then just replaced the images for the continue icon. The close icon hover state works, but the continue icon's hover state does nothing.

File attached. Any insight is much appreciated! 

Thank you!
