Filter report on date: slicer for date range

Hi guys,

I'm working on a report which shows me when our employees have been sick and for how long. The absence has a startdate and an enddate. It must be very simple but for some reason I don't get it working.

I have a slicer based on startdate. If I pick the option 'between' I can fill in my daterange. If someone is sick from 1-1-2018 till 31-01-2018 I see this row if I set my startdate on 1-1-2018, but not if I set it on 2-1-2018. This makes sense. What I want to have is an option to see who / how many employees were sick on a certain date. So I have to get a range from startdate - enddate for each employee. If 3 employees are sick from 1-1-2018 till 31-1-2018 and I pick the date 10-1-2018 I want to see the 3 corresponding employees.

I've tried changing my slicer, not basing it on startdate but I made a datetable but this doesn't work. I hope this is clear. I've attached a pbix with testdata, this will explain a lot.

I hope you guys can help me, thanks!
