Search Button Not Formatted Correctly

Hi

For the Account page, when logged in, if I go to Contact link and Account child link it takes me to this page.

There is a red search button that is usually a rectangle. Right now it is displaying as a small square.

Please refer to screenshot: http://www.screencast.com/t/cRWMIUUy.

This is the page: http://www.taggedbyanangel.com/account/

Please advise on how to correct this glitch.
