translation doesn/t work

Hello,

I try to omntegratea woocommerce shop in my website. Most of the translations work, but on the shopping cart page, German and English are mixed. I have tried all the translation recommendations (Loco translate etc.) recommendations I found online, none helped. I would also change the settings via SFTP in the CSS of the theme or plugin, but I don’t know where to find them.
