Index commas render in wrong font

[Karen Robbins]

Hi Framers,

My index style is a comma + space between the entry text and the 
associated page number. The paragraph format for all index levels is 
Helvetica 7 pt. Entries with only one page number render correctly. 
Entries with two or more page number references don't: the first 
comma renders correctly but subsequent commas (between page numbers) 
render as, and have a character format of, Times New Roman 12 pt.

Fixing hundreds of these manually is not an option. Fixing this using 
"default font" from the character format catalog or from the 
character designer by changing the family and size means changing the 
entire index to one (wrong) font/size/style or selecting hundreds of 
individual lines to reformat.

Is there a way to stop this error in the first place? If not, a 
better way to fix it?

Thanks,
Karen
