Show latest date of occurence

Hi all,

I am trying to find out a way how to display the latest date of occurence from a specified list.

My parameters from a datasets to make the filter are:

Incident Type.Type: Personal
AND
Incident Type.Subtype: Restricted Work Case OR Lost Time Accident OR Medical Treatment
AND
Incident Report.Incident Party: Company

Which I took care of on a visual level filter ( I am using the Card type visual).
However, when I specify that I want to see the last date (or the first date) it is not displaying the correct date. This is what I got with the last date:

29-Oct-15

And this is with the first date:

15-Oct-15

But the correct date should be:

27-Jul-16

Anyone has any suggestions how to fix it? Or how do I do that? 

Thanks a lot,
Kristina
