There are a few potential reasons why an event might disappear from the Lexicon and Events page search but still exist in the activity feed: 1. Inactive Events: Mixpanel automatically hides events that have not been fired within the last 30 days from report dropdown menus and searches. As stated in the documentation: "Mixpanel's report dropdown menus hide events that have not been fired within the last 30 days. The events will still be available in the project's raw data, but will not be visible in the UI." Debugging: Validate your data and troubleshoot your implementation2. Hidden Events: Project Owners and Admin users can manually hide events in Lexicon. Hidden events are not indexed in the event menu in the query builder but still exist in the raw data. As mentioned: "A hidden entity will not be indexed in your event/properties menu in the query builder. Any inactive events and properties will also be hidden." Lexicon: Describe your events and data using a dictionary3. Event Approval: If your project has Event Approval enabled, new events are hidden by default until an admin reviews and approves them. This feature is described as: "Event Approval is another valuable addition to Mixpanel's data governance toolkit. This feature notifies admins about newly tracked events and hides them from other collaborators by default." Unlocking better data governance with Anomaly Detection alerts and Event ApprovalTo find and use a hidden or inactive event, you can search for it by name in the dropdown menu and click "Show Hidden Events/Properties" to reveal it. If the event is truly missing and you believe it should be visible, you may want to check your Lexicon settings or consult with a project admin to ensure it hasn't been intentionally hidden or dropped.
