Many thanks for suggestions but I have already these translations in my learnpress-de_DE.po file but these are not affecting.
Can you check that page and let me know how to go further. are these words are coming from database something like this or can be translated from the learnpress-de_DE.po file?

All the other learnpress plugin is translated successfuly.
