To remove duplicate event values in Mixpanel, there are a few approaches you can consider:1. Event Deduplication: Mixpanel offers an event deduplication feature that prevents duplicate events from being recorded. This is done by using a unique $insert_id for each event. If an event with the same $insert_id is sent multiple times, only one instance will be recorded. Here's how it works: - Include a unique $insert_id in the properties of each event you send. - Mixpanel will check for duplicates based on a simplified version of the event object. - Duplicate events are marked and deleted within 24 hours.

This should be used cautiously as it permanently deletes data: - Use targeted event property filters to identify and delete duplicate event data. - This is recommended for scenarios where duplicate events were ingested due to implementation issues.

Merging Events: If you have similar events from different sources (e.g., "Purchase" from iOS and "purchase item" from Android), you can merge them in Lexicon: - Select the events to merge in Lexicon. - Click the "Merge" icon and specify which event should be considered the new unique event. - This doesn't affect raw data but streamlines analysis by treating merged events as a single event.
