I am looking back at an old event that hasn’t fired in about 60-90 days and whereas I used to be able to breakdown and filter this event by event properties, I can no longer see the event properties. I can see them when I export the data using JQL but really need to be able to create a specific report in the mixpanel GUI using these properties

Hi
If an event is not fired within the last 30 days, Mixpanel automatically hides it in the dropdown menus to help declutter and to minimize loading time. There are two ways to get the events to show up back on the UI.
First, if you find that an Event, Property, or Property value was hidden that you would like to select in the dropdown, you can force it to reappear by firing that Event or Property again. Once it’s been re-triggered, it will reappear in the dropdown with all historical data.
If the automatically hidden item in question was an Event, note that once an Event gets re-triggered, you can create a Custom Event with the unfiltered, historical Event selected as the sole parameter. Custom Events are not automatically hidden after 30 days, so moving forward, this will prevent the Event from being removed from dropdown again.
The second way to make show up on the UI if you know the exact value of the property, you can specify the event and property by clicking the type of property you are looking for (event/user) > typing out the property name (case sensitive) > clicking the "+ property_name" which allows you to specifically use the value you entered.
For example I have a test project I have not used in months and the event Checkout with event property Products that is not showing up in the UI. In the giphy below I have made them show up by clicking the “+ Checkout” on events and the Breakdown “+Products”.

The second way is a quick way to make it show up, for long term I would suggestion doing the first way.
Hope this helps!
