Hi Michael,
Have you contacted the langauge pack maintainers?
I see you are contributing to Moodle for Workplace. That langugage pack is something special - only workplace-only and changes to the standard ar language pack should go in there. All shared strings should go to the standard ar language pack.
The workplace language pack is maintained by companies offering Moodle Workplace (see https://docs.moodle.org/403/en/Translation_FAQ#Why_do_other_languages_have_child_languages.3F)
Kind regards
Koen
