vSphere tags in vRO ps 6

Hi best Community,

There is a  "Summary | vSphere Tag"  Metrics in vROps which let me use  "Summary | Custom Tag | Value"

and the same metric I can found it the Policy settings. But! when I am trying  create a view so you only see the "Summary | vSphere Tag" no Summary | Custom Tag | Value"

Similarly, i create groups and to withdraw the machines in the group. You only see the "Summary | vSphere Tag"

Is ther any reason behinde that

Many thanks
