The good news is that those 11-14 are correctly input Endnote fields, but I don’t have a clue why they won’t reformat! Does anyone else have endnote on their machine, that you could try (with access to your library)?
This one looks a bit weird: Helse- og omsorgsdepartementet, 2013 #29 but other than that… it doesn’t look wrong.
You could try the “clean up” step of selecting all the text in the unformatted version (Ctrl+A on a PC) and then Ctrl+6 to remove any remaining corrupted field codes. Then try to update. Otherwise I would make that call to Technical Support directly
1-800-336-4474 option 4 then 1
