title: Filled map by postal codes for Poland shows whole country
body: <p>I have postal codes for Poland (more than 22000). If put into the filled map in Power Bi – it is showing the whole territory of the country, even though if I put codes’ aggregated territories into the legend.
  The communication is as: ”too many values, not showing all data”.
  If filters are put to reduce the number of data the system shows as follows:
  “more location data is required to create a filled map. To create a filled map, the location data should include Bing Map-supported geographic data, such as country/region, state/province, or postal code.”
  I would deeply appreciate for any comments or help to solve this problem.</p>
