How to mark trailhead unit as Read?

I do not see any option on the page, however the challenge section says that 'This unit doesn't have a challenge. You can still earn points by marking the unit as read. Good job!' 
This is for Creating and Customizing Lightning Apps trail.

Hi all - sorry for the trouble. This unit is currently missing the associated challenge, and we'll need to make a fix before you can complete the module. We're targeting 11/1 for the fix. Please hold off on this module until then. My apologies again for the inconvenience.

Hi @Chris,
This module is required to be completed to open the lightning experience specialist superbadge challenge. So do I need to wait till 11/1 for that to open?

Hi Amit - that's when this issue is scheduled to be resolved, so yes, you'll need to wait. Again, we're sorry for the trouble.
Was about to raise same issue/question but saw that this topic was already refering to my issue.
I understand that the clallenge is not open from Chris comment.
But would have been great to have another message than the confusing one :)

Mark as read. But where ?
