If you want to export parts of an obj file to make morphs externally, the figure/object has to be in its absolute ZERO, position.

Remove all IK
ZERO all joints with the joint editor.

Set figure at Trans 0.000 for X,Y,Z,

Set/check hip at Trans 0.000 for X,Y,Z,

Now you can export the parts of the figure you want to morph externally.
The figure obj HAS to be in the exact neutral position, (as the obj file in the Geometries folder is), before you can export parts to make external morphs.

Some apps require an extra step as they loose the uv data.
If you loose the uv data, take the morphed obj file through uvmapper to import the uv data from the origional obj file.
