BrowsingDataLifetime not working

Hi, 

we just implemented the new BrowsingDataLifetime Policy for Microsoft Edge like described here:

https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#browsingdatalifetime

The clients are getting the policy and i can see the settings also in the registry of the client, but my browsing data will not be deleted.

Here are the settings which we are using:

[{"data_types": ["browsing_history"], "time_to_live_in_hours": 1}, {"data_types": ["download_history", "cookies_and_other_site_data", "cached_images_and_files", "site_settings", "hosted_app_data"], "time_to_live_in_hours": 1}]

I than visited some sites, downloaded some testfiles, stored some cookies, but after the browsing data does not get deleted.

Has anybody got this policy working?
