That shouldn't be happening - can I take a look at the site to see what's happening?

It should be switched off by the following CSS on line 732 of the stylesheet:

.teaser h5.description {
display:none;
}

So I guess the .teaser class isn't being called since the info is being displayed by views. You could try adding this to the stylesheet:

.view-list h5.description {
display:none;
}
