Not showing as complete?

[ProfeSwanCHS]

I am new to using Duolingo in the classroom. I have recently given my first assignment. Some students are showing "Not started" however, when they show me their phones, the assignment has been completed. How do I correct that on my end?

Are those students doing the same course as the course your classroom is set to use? Their target language and base language both have to be the same. They will be able to add as many courses as they like, alongside the one in your classroom.
