RANKX with repeated values

Hi there,
thanks for your reply! I will provide the dummy data with my expected outcome right here.

I would like to see in how many countries different employees have worked, based on Month/Year, so I can filter on Month Year. As you can see in the picture I already tried a few things but it does not work out yet. 

First column is my employee, second the month year and the third country name. The outcome i created myself is that when the country changes, it give RANKX +1, BUT when someone goes back to a country he worked in before, it may not show +1 but +0.  I attached the Excel file as well, but as you can see in the screenshot down here, it needs to show 1 till 3 instead of 1 to 4. 

As you can see, the employee goes back to the Netherlands in 01-06-2020, so PowerBI thinks the country changed because it goes from Denmark to the Netherlands, what I would like to see are some other 2's. Because he worked in the Netherlands before.

I need to see this per line because when we filter on 01-07-2021 I need to see that employee 833 worked in 3 different countries, and not 4 as I have in my dummy data. Hope this is clear enough, and someone can help me.
