Customized Translation doesn’t work

Hello,
i have a problem with the translation and the customization of the consent box text. I’m installed the Klaro Plugin and downloaded the .po file to translate the text. After translation i renamed and saved the file. So i uploaded the renamed .po and .mo file to the language folder on the webspace. But it doesnt translate the consent box text. Is there anything in any file i have to do to get the full translation in German or any other hing i have forgotten?

Thanks for your help!
