Data-discrepancy issue between Prometheus and Influxdb

Hi Grafana Team.
Hi Influx team.
I have data-discrepancy issue between two different type of data-sources → Prometheus-DB (Grafana) and Influx-DB (Grafana)
I have a Grafana with Prometheus as datasource and another Grafana with Influxdb as datasource. Influxdb collects data from Prometheus; but if I run the same query on both Grafana, I don’t get the same values in the data.
There is a data-discrepancy on Influx-DB querier.
Do you know what could be happening? or wich parameters I should check?
thanks in advance!
