After we looked into the situation, we found the issue resulted from the changed “Text domain” field, and also you have removed the “languages” folder.
It does not work because you have the same issue, the “Text domain” field is still changed and there is no “language” folder. The fastest way to fix that is to reinstall the theme.
After reinstalling the theme you should synchronize all strings in the “Loco Translate”, so I did it on your side and all strings from the theme appeared.
