Provisioned dashboards disappear from time to time

Hello,

We are facing an issue where some of the provisioned dashboards disappear from the UI without a change introduced. All our dashboards come from an internal GIT repository and changes are strictly monitored…
A dashboard is in the file system, but not displayed in the GUI (while being visible before that). In order to make it visible (again) the workaround is to open the file and change the dashboard title tag slightly (by adding a symbol to the name). The Dashboard appears after the change. Then we change the name back and it stays visible with the original name.
This happens only with some of the dashboards and we have been unable to pinpoint a possible reason for this. The behavior is being observed with quite a few Grafana versions (we always run the latest one)…

Have you seen this happening and do you have an idea/proposal about fixing it?
