extra button on hero

I’m using several hero images on this site to build CTAs. Most are working great, but I’m having a weird issue.

I have a row with 3 heroes. The first hero is getting a weird ghost

<a> </a>

tag inserted before the button. This also happens to the first hero if I put two heroes in a row with three columns.

The site is here http://larsonupholstery.com/commerce/leather-seat-covers/

Anyone have any ideas?

Thanks!
