after editing *.pot file nothing changed

Hello!
I have an issue, about my wordpress site.
I’m using the Darmstadtiumoid theme.
after I finished translating the Darmstadtiumoid.pot file and overwrited with the original, nothing changed. I activated a different theme then reactivated Darmstadtiumoid theme, but still same. Any one has an idea what can I do?

Please help thanks!
