Saved Segment Not Working

pspan

I'm running into a problem with a Saved Segment that is not working as expected.  

I have a list of internal users that I actively maintain to ensure charts show user behavior (not internal usage).

 

My Weekly Active Users chart has the “exclude” segment applied, but the chart data contains excluded users.

Hi pspan - thank you for writing into the Community! Since I’m not sure exactly what your chart setup looks like, I’ll try to explain what I think is happening -- 

Amplitude is an event-based platform, which means that events are logged with the event properties and the user properties present at the time the event was fired, and this is what populates in the chart.

Let's say you have a group of users who fired event A, and you are analyzing event A in the Event Segmentation chart. At the time they fired event A, their user property gender had not been updated. But now it is updated. Even though gender is updated now for the users, their gender would pull up as (none) when looking at event A since there was no user property associated with gender at the time event A was activated.

So in your situation, perhaps the users you are excluding (user property: email) do not have this property sent with the event you are querying on, which is why they are populating in the chart.

I'd recommend taking a look at these articles to dig deeper into this topic:

Please let me know if you have any questions!
