I want to filter and include only specific values on my query but I can't see the rest of the attribute values. Why don't attribute filters show all values available?
The filter option shows all available values for the ticket field you want to filter. However, the page can only accommodate the first 100 values. Click on the arrow at the bottom of the pop up to show the rest of the values available.
