[Resolved] Translate woocommerce string

Hi there, I'm having problems translating certain WooCommerce strings. I tried translating them via the String translation with no success. I also already followed multiple WPML tutorials:

https://wpml.org/documentation/getting-started-guide/string-translation/finding-strings-that-dont-appear-on-the-string-translation-page/#scanning-for-hard-coded-strings
https://wpml.org/forums/topic/my-account-page-i-cannot-translate-strings/

But with no luck unfortunately. For example, on hidden link it should not be "In stock" but "Auf Lager".
