This should be easy to fix. Try the following steps:

– Remove Y and X trans from morph

– Export to Hexagon via bridge

– Zero figure in Daz

– Import (morphed) figure back into Daz

– Save as new morph

You should be able to overwrite the old morph this way. If not, there are a couple of workarounds – just let us know.

PS – I've had trouble getting help from the Daz forums, too. Glad you decided to post over here! :)
