Alert with no value

According to screenshot, we have default configs for pushing notifications

I would like to disable it, cause i got the alert without value
Screenshot 2022-02-01 at 12.20.47
version of grafana 8.3.4

this is log from grafana

t=2022-02-01T13:30:02+0000 lvl=eror msg="Range query failed" logger=tsdb.prometheus query="burrow_kafka_consumer_lag_total{cluster=\"kafka\", consumer_group!~\".*amazon.*\", consumer_group!~\".*burrow.*\", instance=\"<dns>:80\", job=\"dev-burrow-kafka\"}" err="Post \"http://<dns>:80/api/v1/query_range\": EOF"

This false positive alert is super annoying, it’s not a NO DATA state either.
