Imbalance 2 WP - Posts Only Showing In First 2 Columns Instead Of 4

Hey I'm trying to put together this e-zine but for some reason my posts are only showing up in the first 2 columns on the left instead of the 4 columns available.

I've googled about and tried deactivating my plugins but the problem is still there.

I'm pretty stumped as to what might be causing it so I appreciate any help.

Thanks.

EDIT: Solved
