[1.8.11] Date filter is reset when all results are in

Hey there, it seems like there is an issue with the date filter, here's what I was doing:

• Deactivate the fast criterion
• Do a search
• After the side panel appears and the precise target filter appears, filter for a date that is somewhere in the past. The results are filtered
• After the last source finishes loading, all results including outside the filter are shown. I need to re-trigger the filter, by changing the date, to only display the ones I'm interested in

I can't reproduce it easily, but it did happen once...
