Need help with Support System .po translation file

Hi all, im translating .po file of support system plugin to my language, i have duplicated the .mo file and renamed it to match my code location at the end of the file. I have now 70% of this file translated and working, but the only lines which its not translating is the user email´s notification....
I have translated the user notification content emails and it still send the emails in english.

what possible could be wrong here?

im using .po editor virtaal for this translation also

Thank you
