Edit/Extend Event Recurrence in Database

I am trying to find a quicker way to extend recurrence end dates than opening each event on the frontend. I have over 300 recurring events, and would like to reset their expiration dates directly in the database. I have edited the year in the field ‘recurrence_rules’ in the table ‘wp_ai1ec_events`.This change is not showing up on the front end. Is there something else I need to do to instruct the plugin to create the new posts?
