You may want to reset one or more event results from a Database in which some events were seeded or run. By "reset" we mean remove any Seeding or Result information for all rounds of a selected event. If you have "accidentally" seeded or run an event(s), this is a great way to reset those events for the meet.
From the Main menu Bar, click on File / Purge /Reset Event Seeding and Results. Choose from the Event List and MM will reset the status of those events to Un-Seeded and will remove the seeding and results data. This will not remove the entries.
