Gridmarket Sidebar Acting Funny

Hey there–

At this page:

You can see the sidebar is all the way down at the bottom on the left side of the page. I’ve been working on the contents of the store and how they display, but I didn’t do anything with the sidebar and now all of a sudden it isn’t floating up to the left as it should beside the product listing.

If anyone could point me to how to fix this, I’d be very grateful. Thanks!
