Hi Clark W., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so. In case AI cannot answer your question, feel free to reach out to Mixpanel support at mixpanel.com/get-support. If you have follow-up questions for this thread, please tag me again with your question: @kapa.ai <follow-up question> 👋
Feel free to ask a follow-up question once I've answered by mentioning me with @kapa.ai
There are a few Mixpanel‑specific reasons this can happen even when you see events in Data/Events:
1. Event is “inactive” (older than 30 days) - Events that haven’t fired in the last 30 days are hidden from Lexicon and from dropdown menus in reports, unless they’ve been modified in Lexicon (description, display name, hidden/shown, tags, etc.).[Debugging guide] - To surface it again, send that event once more; it will reappear in Lexicon and dropdowns.[Debugging guide]
2. Event is explicitly hidden in Lexicon - Admin/Owner roles can hide events in Lexicon; hidden events won’t be indexed in menus and are excluded from query results like “All Events.”[Hiding data] - In Lexicon, search for the event name and check if its status is “Hidden”; if so, unhide it.[Hiding data]
3. Event Approval is enabled (Enterprise only) - If Event Approval is on, new events are hidden by default until an admin reviews and marks them visible.[Event approval] - An admin should go to Lexicon → “View New Events” and mark the event as visible.[Event approval]
4. Very old imported / warehouse data - Historical events older than 30 days (e.g. from Warehouse Connector / migrations) do not appear in Lexicon or the Events page; they’re only visible via reports like Insights.[GA migration validation]
What to try now
1. In Lexicon, search for the exact event name (case‑sensitive) and click “Show Hidden Events” if available.[Hiding data; Debugging guide] 2. Fire the event again now and then refresh Lexicon. 3. If you’re on Enterprise, check if Event Approval is enabled and approve the new event.[Event approval]
If you share whether these are live events or historical imports, I can point to the most likely cause among the above.

the events are less than 2 horus old
Let me check the knowledge base for you again. One moment! 📚
Since your events are less than 2 hours old and visible in Data → Events, ingestion is working; this is almost certainly a Lexicon visibility/UI issue, not a tracking issue.
Run through these Mixpanel‑specific checks:
1. Check if the events are hidden in Lexicon - Go to Data Management → Lexicon → Events. - Use the search box with the exact event name (case‑sensitive). - Turn on “Show hidden events/properties” if you see that option. - If the event’s Status is “Hidden”, select it and click Unhide.[Hiding data]
2. Check for Event Approval (Enterprise only) - If Event Approval is enabled, all new events arrive hidden by default until an admin approves them.[Event approval] - In Lexicon, look for an “Event Approval” / “View New Events” section. - If your event shows with a “New” tag and is hidden, have an Admin/Owner mark it Visible.[Event approval]
3. Confirm it’s not an “inactive” name mismatch - In Lexicon search, type the event name exactly as it appears in Data → Events (including case and whitespace). [Check hidden] - If a slightly different name (extra space, different casing, etc.) exists, that’s a different event in Lexicon and will not show your new one.
If you’ve confirmed:
- the event is not hidden, - Event Approval is off (or it’s been approved), - you’re searching with the exact event name,
and it still doesn’t appear in Lexicon after a few minutes, then the docs don’t describe another UI‑side reason for such a short delay. In that case, take a screenshot of:
- Data → Events showing the event name and timestamp - Lexicon search results for that same name
and contact Mixpanel Support so they can inspect your specific project state (this kind of Lexicon indexing lag is not documented in the sources above).
