Hello @Nikka79,
We understand that you are having an issue with the translation files being in the wrong folder, which causes them to be overridden each time you update the theme. We suggest that you keep the translated files in the wp-content/languages/themes/ folder so that they will not be lost when you update the theme.
For further information, please refer to the following articles and threads:
