Issue times series aggregation with Zabbix database

Hello, my problem is after upgraded grafana to 4.6.3 i can’t create anymore table panel with text data source from zabbix in times series aggregation, the data is visible only i don’t use series aggregation. The data is not a numeric value and i can’t select metrics data but it was no a problem with the previus Grafana version. Colud you help me?
