I use json/csv importer to import trading data and this date issue is breaking my dataview queries.
On the screenshot you can see that my old imports (left) display properties in the correct format (yellow)
New imports (right) use slashes even tough the handlebar template is set to date and displays it correctly.
If I use '=this.openPeriod' is also shows me the dates in the US format on the right and German format on the left
On an related issue I also can not import my CSV rows as dates anymore. (purple) They all become underscores as file.name which now renders my queries obsolete… : (
