Hi Maurice,

The "description" field seems to actually be the text for the button to continue to the next page in the lesson, which is probably why you are seeing it centered and overflowing off to the right. I think the field you want to be editing here is not "Content 1 Description" which should be something simple like "Click here to continue", but the field above that, "Page contents".

So I think the way this page is designed to work is that you have explanatory text in "Page contents" and then can have branching buttons leading to up to 4 different pages elsewhere in the lesson, with the text for each jump button being set in Content 1 Description, Content 2 Description, etc.

The Moodle documentation for the Lesson module may provide further help:
