Missing field name in Grafana alert rule

Hi. Im new to Grafana and my problem will sound pretty basic but I couldn’t find a solution online.

Basicaly when I setup my dashboard, run a query on an InfluxDB data source and filter for certain fields, the query returns the fieldname with all its information. When I run the same query by creating an alert rule, i get mqtt_consumer with all of its information instead of the fields name.

So on the dashboard itself the query shows me: Sensor1_hum_CNC{host=foo, topic=foo}

and on the alert rule page it shows me: mqtt_consumer{host=foo, topic=foo} running the same query.
