ElasticSearch template varible "On Dashboard Load" reverts to now-6h always?

After some testing I’m unable to get a template variable of type “Refresh on dashboard load” to do searches other than “now-6h”. It does not adhere to the dashboards own default timepicker, rather now -6h every time. That time range (now-6h) seems to be a default also when you start creating a new dashboard. I have not found a setting for that from grafana.ini

Could someone confirm or provide advice on this?
