Duplicate timestamps values in grafana and thanos datasource showing single timestamp value - monitoring

Question

Grafana showing duplicate timestamps values and Thanos showing the correct single timestamp value. I'm hitting a single curl request for application API Thanos showing the correct value but when I'm running the same query in grafana it shows two count values. I'm using telegraf agent for collecting metrics in prometheus.
My whole setup is running in Kubernetes and I'm using telegraf statsd for application monitoring.
