I cant see the plugin theme in network

Hi

I have some problem with the theme setup.
So in the https://simplylearn.no/wp-content/plugins/coursepress/2.0/themes/coursepress/style.css file I have change the header to
Theme Name: CoursePress original
To see what are the original theme.

But in network settings I do not see the theme: https://simplylearn.no/wp-admin/network/themes.php?theme_status=all
Why?
