Kubernetes for the Absolute Beginners - can't complete?

After going through the whole course the status is 98% Complete 69/70 Steps.
Did I miss something or is this an error in the content?

Sometimes people don’t do the feedback, so you might have to mark that as completed.

Double checked and it seems to be some mismatch in the course.

Seems like something is missing in chapter “Microservices Architecture”

I would go through each lesson in Microservices and mark them as complete manually again.
