Most of this is syntax errors in classes. Sometimes, a glyph may exist in more than the allowed number of classes [one left and one right or else only one both] Be sure you use the inch or straight up ascii apostrophe instead of the curly typographic variety in your classes.
Also, look for final semicolon and any other duplication which stops FL in its tracks.

Also, try WINDOW > PANELS > CLASSES > Clean Up Classes, just for grins.

I think there is a bug somewhere in Fontlab that jumbles something in or with the groups when you generate a new kern feature in Kerning Assistance. I have had the same issue, fixed it, then generated a new kern feature, then the issue appears again.
