Coordinate conversion and plotting in Google Earth

Hi,

Could you please help me with the following:

Seemingly I set up gINT properly so it can plot the locations in Google Earth. In the project table I chose the Coordinate System, and in the WGS84 coordinates got converted in the Point table.

However, when I send them to Google Earth, the locations come up with some offset (about 200m).

When I use the East, North coordinates and generate the kmz file from ArcGIS, the locations come up where they should be.

So I reckon there's some problem during the conversion.

Any idea how to fix this problem? 

Many thanks!
