Issue - Refinement web part with date bar

Hi,

I want to use the date bar visualisatisation for a "custom" managed property but is does not show as expected.

We have news pages related to a new content type with the default field ArticleDate. This field is mapped to a default managed property "RefinableDate00" to use in a search refiner. When I configure the refiner the bar only shows years (2.015 - 2.016) and not the usual labels as last week, last day,...

After googling I found some similar issue but all solutions did not change anything. In one blog I read that normally the RefinableDateXX managed properties should work fine in a refiner with bar and graph.

Anyone experienced the same issue and perhaps knows a solution or possible solution to check?

Kind regards.
