Geomap issue about geojson interpretation

Hi experts,

I encounter a geomap issue about geojson interpretation.

My DS version is 1.6 SP1 Patch 2.

Here is my geojson.

{"type":"FeatureCollection","features":[{"properties":{"name":"Hangzhou"},"type":"Feature","geometry":{"type":"Polygon","coordinates":

[[[121.4208984375,25.34402602913433],[119.88281249999999,23.180763583129444],[120.91552734375,21.922663209325936],[121.9482421875,24.806681353851964],[121.4208984375,25.34402602913433]]]}}]}

It works well in geojson.io and GeoJSONLint - Validate your GeoJSON

However, in Design Studio, Geomap draws the chart reversely.

I've spent quite some time but not able to figure out how to fix this.

Sample application is attached.

Appreciate any help. Thanks.
