When I upgrade the Pro theme from 2.2.5 to 3.1.1. the backend editor (WP Bakery) mikses up the code. See screenshots.
Krik.no - live - still running on Pro 2.2.5
http://test.skarp.no/kriktest/ - staging - updated to Pro 3.1.1
Note: There are shortcodes inside text elements after updating. And the right column looks empty in 3.1.1 version, but there are some buttons there.
After updating to Pro 3.1.1 the news articles display the content twice http://test.skarp.no/kriktest/800-krikere-er-klare-for-explore/
