K. Made it home and did what I said I was gonna do above. Please refer to my disclaimer above before you do this but it worked for me:
Go to the UI/FetishNightfall folder and delete these two files:
eq2ui_mainhud_groupmembers.xml
eq2ui_mainhud_raid.xml
Edit the eq2ui_mainhud.xml file and add this line where it looks like it would fit alphabetically:
<include>eq2ui_mainhud_threat.xml</include>
That fixed it for me. Your mileage may vary.
