I have a blend of two data sources, Users (postgres connector) and GA4 Events (Big Query).
I am showing the event count for custom events, but I noticed that the event count metric is wrong when the blend has an Event Time dimension from the Events data source. If I remove Event Time from the blend the event count is correct. Sadly I need the Event Time in another table so removing it is not a an acceptable solution.
Why is this happening? How can Event Time dimension in data source affect event count if I set up date range in table to be i.e. Last Month.
