Hi ,

I have created a field called **Client-Correlation-Id** using KV filters , the field name is Client-Correlation-Id, the field is properly parsed by logstash and i can see that field being available in the left pane. But when i try to visualise that field, i dont see that field in the drop down for Unique count visualisation.
