VM appears in drop-down list, but not in metrics

[scaleoutsean]

• If a VM is named performance, it seems something scrapes its metrics. Notice how it appears in the drop-down menu, but in the panel its metrics are completely absent. This is a vSphere 6.7U3 cluster, with only one ESXi host, so all VMs are on the same cluster and host. I cloned this VM from one of the other VMs that appear in panels just fine.
• v0.8a (back end: graphiteapp/graphite-statsd:1.1.6-1)

I need to check if performance may be a "reserved" word in graphite...

In other words, I don't see why vsphere-graphite wouldn't consider it.
