Alerting Evaluation Value is Different from the actual value - Infinity Data soure

Hi,

I have this alert query which fetches last 3 value and average it by 3 if the avg value is more than or equal to 1 it should alert.

I can see the below alert triggered but the value which is showing for the query A is actually wrong which resulted in false average value.


When I checked the actual value reported at 10:06 it is 1.53 not 5.8

PFB alert query

@jangaraj @mycchung Highly appreciate it if you could help me resolve this.
