Hello,
Go to WPML > String Translator > loos for the strings you need to translate, for example https://gyazo.com/82c2ab5d76b32d5e069c2898d32c5629 and translate that. What other details do you need?
I added screenshot for your every question. So, did you translate things that I mentioned there? What other strings do you still have untranslated after that?
Regards
