Chrome button:hover buggy?

So if you take a look here and hover over the Preschool ‘Learn More’ button and the Teams ‘Learn More’ button in Chrome, you notice that the during hover the text disappears. I have the color on hover set to be ‘#FFF’. In FF and IE, I don’t see any issues. What’s queer is that this hover state does not act up on the Xcel Program ‘Learn More’ button.

Using Chrome’s Developer Tools and checking the :hover state, I’m not seeing any problems. The code is the same. The only difference is the rotation and background colors.

Anyone see why the two other buttons aren’t working?
