Broken sidebar showing below content

In some views, not all, I see a broken sidebar displayed under content. For example:

https://americandreamcustombuilders.com/features/40-gal-electric-water-heater/

The problem doesn’t occur in the main or listing views:

https://americandreamcustombuilders.com/homes/inventory/
https://americandreamcustombuilders.com/listings/jefferson-manor/

I have reset permalinks, but that had no effect.

It appears to be using a full-page view, but still inserting the sidebar below. Please help.

Thanks!
