I'm sorry to see the inconsistency in the bottom area of this template. It looks like you are using one of our template gallery templates Boulder Park. I'm passing this along as feedback to our team to see if we can make changes to have this format properly.
For now I would suggest either using one of the custom templates you have saved or a different template found from our template gallery.
Additionally if you switch to a three column format then back to right column you should see this format correctly.
Thanks for patience on this one and let me know if I can answer any additional questions!
