[CoursePress Pro] Missing language string

Hi, I am currently translating CoursePress Pro into Danish, and I've come across a missing language string in a highly visible line of text ="About the Course". Check it out here on this live test page: https://skills.techhytten.dk/courses/test-kan-slettes/
I cannot find this particular string in Poedit, hope you can help/resolve.
Best regards
Kristian
