Species latin name exported to a wrong format in better bibtex
I had my Latin names, such as Amaranthus rudis written as Amaranthus rudis in Zotero's title field. These were then saved as {{{\emph{Amaranthus}}}}{\emph{ Rudis }} as I exported to better bibtex. I had expected {{{\emph{Amaranthus}}}}{\emph{ rudis }}. What have I missed? Thank you.
