I am a convert from PC to Mac. Doing OK, so far.

When I open up a .doc or .docx file in Nisus, the footnotes are there but they have no numbers. Rather they all have same code
--- NOTEREF _Ref319262934 ---
both in the main text and at the beginning of the footnote, where the number should be.
Is there any way to globally correct this, or must I cut and paste each one into a new Nisus numbered footnote?
Thanks for any help.
Isaac
