Microsoft Office 2013 all the way to 2021 LTSC has a bug in the spanish language grammar and orthographic checker. The grammar and orthographic checker does not detect and mark the following words:doscientestrescientescuatrocientesquinientesseiscientesSetecientesOchocientesNovecientesCorrect words would be with "a" or "o" as the last vocals:doscientostrescientoscuatrocientosquinientosseiscientosSetecientosOchocientosNovecientosAll of the former are the spanish names for numbers representing hundreds.
