Hi Peter:
The root of this question (and the two you asked in your email to me) comes down to formatting inconsistencies between the .fm chapter file and .fm inset file being pulled in. You will want to standardize all of the formatting between the two files to be able to move forward confidently, as per @Winfried Reng and @Jeff_Coatsworth.
I think they set you on the right track, and importing the x-ref definition solved the full stop issue. 😊
To address the additional questions from your email:
Both files are set up in Format > Document > Footnote Properties to assign a style called TableFootnote to all new footnotes. However, in the inset file, the existing footnotes have been assigned Table Footnote and have overrides and character styles. FrameMaker is carrying in the duplicate style name and the overrides from the inset to the the chapter file, so that even though new notes will be Times New Roman 10 in both files, the existing notes are Arial 8.
- In the inset file, remove the overrides and assign all the notes TableFootnote. Remove Table Footnote from the file. Then remove and re-add the x-ref to table footnote 2 (it's holding on to the old formatting).
- In the chapter file, remove Table Footnote.
- Update the inset.
You should be good to go.
