I checked the site and looks like the site HTML is all messed up somehow. One of the div elements is not closed (entry-summary element) which breaks the layout making the sidebar etc. to be pushed to the bottom of the post instead of being shown as a sidebar on the right. Did you add any make changes to the plugin code? Pls check.
Sorry I didn’t get back to you sooner. After doing more digging it appears that it’s a conflict between the WooCommerce Bookings and WooCommerce Catalogue plugins.
When the WooCommerce Catalogue plugin is deactivated all bookings products revert to the proper layout structure. I’ve filed a ticket with WooThemes about the issue and also referenced your advice that the “entry-summary” element is not closed.
