Welcome back 🙂
If you have a value entered in the event’s ‘Cost‘ field (see screenshot below), the price will display in the list view as shown in your screenshot. Can you temporarily deactivate all plugins other than The Events Calendar and The Events Calendar PRO, visit the ‘Industrial Rope Access Training – London’ edit event page, scroll down to ‘Cost’ and remove the ‘700’ value?

Reactivate your ticketing plugins and visit the list view to see if the price still displays. Let me know how it goes for you.
