Use the "Test Active Discovery" button to make sure you're getting the right instances. You might not need the "auto." at the beginning, i can't test without an arista device.
Once you've got that new clone working, set your threshold on the volt datapoint.
Once that's all working, there's no need to monitor those instances with the old datasource, so go add a filter that filters them out of that one. Something like this:
