Verified Mapshaper JSON coordinates output always shows the same area and it doesn't make any sense


I am somewhat new to PowerBI and want to use it to display different custom areas on a map. 

Therefore, I uploaded the data to mapshaper, created polygons and exported them. Instead of the area I wanted to display, it shows a completely different area (just one polygon instead of about 25) with coordinates that do not even remotely fit mine.

In order to troubleshoot, I created different polygons and they produce the very same result.
I already deleted the PowerBI cache, but the output remains the same.

Can anybody tell me what I am missing and help me, please?

Thanks in advance.

You probably chose a different projection than you should have, and probably dropped some polygon attributes that you shouldn't have.
