Hello.
The issue below was faced only in the version 10.
We noticed that the some values were changed without manual intervention when are imported the dashboard JSON content.
The issue was faced only in the version 10.
Original JSON.
From original dashboard, the values are “prd, dev, ppd, int …”
These values were change to “Production, Development, Integration …” and the dashboard stopped to work.
When he change these values manually to the original values (but i cannot to do this in all dashboards. They are a lot and in multipe Grafana instances 
).
The same issue doesn’t happen in the version 9.
Any help, please?
Thank you
