Shape Map problem

Hello,

I try to make a topojson file from a shape map using Mapshaper. But when I load the file in Power BI its a mesh (shown below). This is the link to the Zip file with the shape map: http://www.imergis.nl/shp/Gemeentegrenzen_2016_zonder_water.zip

I tried the solutions I found in other articles on the forum but with no succes. Does anybody has an solution for this? 

What I am looking for is a map of the Netherlands with al the countys ('gemeenten' in dutch), i cant find it on the web as topojson. 

Thanks!!
