I completed the first 2 modules on the Admin Trail - Beginner but didn't get the points from the first one and when I came back a day later, I see I don't have the points from the 2nd one either. :( How do I keep my points/credit for completing the modules?

Trailhead shows that I didn't complete the chanlenge, but when clicking on the chalenge itself it shows its completed.
it's preventing me from actually complete the module - did any of you had this issue ? if so, how did you solve it ?
