Dashboard shows no data when multiply to a scalar


I tried to run the query, and it shows data already. But then I multiply it to 1e3 and it shows no data. Please help me to take a look, I’m not sure what happen there. Thanks

Grafana version: 9.5.1
Mimir version: 2.8.0

I tried the same thing to the same metric but different label value and it works well btw

I’m not sure what happen there in the first one
