Problem to see items in "Apply to metrics" field under Rules

[ffurlanetti]

Hi!

I'm using the FlowCharting v0.9.1 plugin over Grafana v8.3.3 and I'm facing the following issue:

I created a chart normally. However, during the creation of the Rule, I realized that I'm just able to see information in the field Apply to metrics when I tag just one Host at the Host field in a Query. On this way I can see the items popping up in the Apply to metrics field. But when I change the value at the Host field to /.*/ I can see all items just in the Table View but in this way, I can't see any information in the Apply to metrics field.

Is that a problem or I'm doing something wrong in the query?

Thanks
