I have unchecked the PMM2 default data source from Metrics to some other data source. Now, I am trying to enable it, but I could not save it.

Can someone please help me out change the data source default to metrics?

@Jorge_Moraes After deleting the new data source, which I have made as default, PMM automatically picks the default source as Metrics.
