Guest Disk Queue Metric Missing

Hi all--  Really confused on this one and I'm hoping someone can help.

Looking to pull the guest queue data from vROps 7.0.  The metric is enabled in the policy as seen here:

However,  when I go to browse a Virtual Machine > All Metrics, it's not there.  Yet, if I create a supermetric and just reference this metric's key "SUM(${adaptertype=VMWARE, objecttype=VirtualMachine, attribute=guest|disk_queue, depth=1})"  it shows the data.

What's more strange is if I create a Metric XML and plug the same info in, it says the metric doesn't exist!

[EDIT]

Also, to show the supermetric DOES work using the keyID...

[/EDIT]

Any ideas?

Thanks!
