Grafana template variable not updating

Hey folks,
I am having an issue with Grafana templating. I have a variable in my dashboard which is of constant type. But the problem is, at a point of time, even if I have updated the variable value with a new value and save the dashboard, and when I do a hard refresh, the query is using the old variable value like it takes it from some cache. We are actually not using any caching mechanism. But not getting an idea why this is happening. Can somebody please help with this issue?

  1. It might be be in browser cache clear it once.
    2, Delete the variable save it and create it again
