When I try to replace the description by only "film" on the item Q47494730 I've got the error:
Could not save due to an error.
Item Q489675 already has label "Charlie Says" associated with language code en, using the same description text.
This is the usual error to avoid two item to have the exact same pair label-description *except* that here, the description are different and the error shouldn't occurs. Maybe the system has been changed to not only detect exact same pair (in that case, the error message should say "similar" and not "same") or maybe there is an other bug. Could someone please look into it.
