Power BI Custom Visuals' Community

Drilldown Choropleth Visual Issue:  The following has been noted in using the Drilldown Choropleth Visual for Microsoft Power BI - Filtering on First Level location causes inaccurate Second Level location geographical visual - For example filtering on States results in inaccurate depiction of County level mapping.  Also, if the source data does not contain a complete state-county representation, drilling down on the visual creates similar inaccurate representation of counties especially in cases where counties in different states have the same name.  This could be due to how the Json shape files are constructed, but I experienced similar results using different json files.  I may need to forego using this visual and defer to the Shape File visual which does not offer drill down capabilities.
