Software Versions

Grafana	Zabbix	Grafana-Zabbix Plugin
4.6.3	3.4.6	3.8.1

What did you do?

I try adding a text panel with text metric and settings of table transform with Time series aggrigations and only one column Curent

What was the expected result?

I expect to see metrics with last value.

What happened instead?

Instead it I see dash.

I have the same issue, post upgrade to grafana 4.6.3 and plugin 3.8.1, the time time series aggregation don't show text field.
On zabbix the values are correct.
