issue with shortcode

I need help getting this shortcode to work

<h2>SOUTHWEST CAPE CORAL</h2>
[listings taxonomy="locations" term="sw-cape-coral" columns="3"]
<h2>NORTHWEST CAPE CORAL</h3>
[listings taxonomy="locations" term="nw-cape-coral" columns="3"]
<h2>SOUTHEAST CAPE CORAL</h3>
[listings taxonomy="locations" term="se-cape-coral" columns="3"]

everything in the first location shows as stacked single items and the other 2 show as a 3 column list like they should. What is wrong here?
