Problem caused by an incorrect translation in CiviGRANT
I know the translation of CiviCRM in different languages is done by community members using Transifex: https://www.transifex.com/civicrm/civicrm/

Personally I have never really looked at this but I would reckon contacting the translation working group (https://civicrm.org/working-groups/translation) on MatterMost here: https://chat.civicrm.org/civicrm/ and offer to make this change will probably be a good step :-)
