How do I list event archives and keep right sidebar to the right (not below)?

I am trying to figure out how to get the Events+ archives to show as a list in the left content section of my site allowing the right sidebar to remain. I get the same results when changing the Archive template to Plugin: Default or Plugin: Full Width, which is the events show up full width and push my right sidebar down below.

You can see what I mean here - http://greendogfoundation.org/events/. It would be nice if Plugin: Default stayed to the left. I am using Solostream's WP-DaVinci theme.
