Grafana alert with multiple queries send zero as query response for all when any one of query result is No data

I have Grafana Alert which as multiple queries with ref_ids like “A”, “B”, “C”, “D”, “E”.
In Expresssion(ref_id “F”) I have set input as “A”, Function Sum(), mode Replace Drop Non-numeric Values and Threshold Input is “F”, IS ABOVE 0.
In description, I have printed all queries values as well.
Issue here is whenever any one of queries result is No data then all query result printed as Zero in alert mail. I wanted all query result in alert email irrespective of any one has No data in result.
