Pinterest Button Overlaps

I’m having the same problem as several others – the “bubble” from my Pinterest button overlaps other buttons.

I’ve tried moving it to different locations and get the same result.

If I move it to the top of the bar, the bubble appears outside of the bar.

Here’s my site: http://www.marriedinmilwaukee.com/

Thanks in advance for any help!
