Why are so many morphs being exported?

mrpdean_7efbae9610

When exporting an FBX using the Daz To Maya bridge, I select just a few joint corrective morphs that I need to export:

 

 

 

But what actually gets exported is over 2350 morphs, most of which seem to have nothing to do with the current character!!

It seems to export morphs for every character I have installed.

How can I get it to only export the morphs I have selected and only the ones the currect character needs?

Thanks
