Datasource influxdb not "active" after deployment


When I create datasources via provisioning folder in Grafana v5.4.3 (commit: 6539180) they show up under datasources page.

When I try to use (select DS and create query in a graph) a MariaDB Datasource afterwards, it works without any problems.
But anytime I provision an InfluxDB datasource, they do not show up for selection in a Graph/Query.

Here comes the interesting part: When I provision an Influxdb datasource with: “editable: true” and manually click on “Save & Test” in the webinterface, the datasource becomes working immediatly.

The provisioning template was copied by the example provided by grafana.
Does anyone experience the same behavior with InfluxDB datasources?
