The screen goes blank after the drip navigation is shown again

[Usapuka]

Hello, I have tried the "course navigation", no problem with the "Custom course sections". But in "Front end course creation" I have hidden and then shown the drip feed and now when I create a new course, when I enable the drip feed, the screen goes blank: https://screencast-o-matic.com/watch/crh23EVfw0C. How can I solve this? Thanks, regards,
