[Plugin: The Events Calendar] Help with 3 column theme

First, lemme say I’d be happy to instantly donate/tip (via paypal) to anyone who can quickly help me resolve this silly issue. lol.

The location is:
https://www.chuluotacommunity.com
You can see the theme and the upcoming event listed over at the top right (sidebar).
If you click on the one sample event I’ve entered so far, you go here:
https://www.chuluotacommunity.com/want-to-help-plan-the-geneva-4th-of-july-parade/

The left sidebar is intact, but the calendar is way down below and then the right sidebar beneath that.
Same goes for Events view:
https://www.chuluotacommunity.com/category/events/month/

What code in the theme can I change to quickly fix that?
I’m not a poet (programmer) so I need explicit directions.

thanks,
