Custom shape map

[Anonymous]

Hello, 

I want to create a custom shape map with dutch townships. I have a Topojson file and loaded this into the shape map visual. The result is almost correct but there are some strange lines running to the corner (image attached). When i load the file in mapshaper the map shows correctly. 

I hope someone knows what is going wrong.

Kind regards,

Tiemen

It's a reasonably common issue.  I can't quite remember the exact solution but it's either using the wrong 'projection' type within powerbi (in the format section of the shapemap)

OR the map has to be edited in mapshaper to change the co-ordinate system to wgs84.

Thanks! I used QGIS to change it to the right coordinate system. Mapshaper shows an error
