Issue when placing Xgen descriptor

[bluebyte60]

Not  sure how to describe the issue accurately, so I would like to place some screenshot.  Please see the follow picture

When I trying to place the xgen grid on the mesh, there are some points which are floating and not the same scale. As the result, the hair later generated follow that floating pattern.

Can anyone point me the direction to fix the issue?  Been trying to fix that for hours but no result. Thanks!

I got this problem solved by transferring the descriptors to another mesh. I think there is something strange when placing the xgen grid on high poly mesh. The original mesh used has around 600,000 polygons, later I use a 10x smaller mesh to transfer the descriptors.
