When I set timespan in "url-view" I don't get a result

[pide2000]

When I try to set the timespan I don't get any results in the url view. (url-view = click in the recent view on an url to view all the runs of the clicked url) After clicking on an url i get the following view:

In the graph I just get the values for 16-03-11 00:00 and 16-03-10 00:00 the others don't show up. When I choose another timespan form the search dialog I get nothing. For example last 24 hours. (And yes, there is data for the last 24 hours)

When I choose just one day as "date-range", e.g. 16-03-10, the graph just shows a run at 00:00. I want to see all the calls to url in the 24 hour timespan.
