@dogfishbar my hunch is that you’ve co-mingled team functionality in GitHub.com with the team functionality in Classroom.
If you made TEAMS and populated them with team mates, then that sounds like you used the Team functionality on GitHub.com.
GitHub Classroom’s flow is that students opt-in to groups on their side, teachers don’t assign them from that interface. I’ve looked up your Classroom, and the only teams that you’ve made in Classroom are TAs.
My suggested fix atm is that since you only have 5 teams in GitHub.com, go into their repositories and add them as collaborators manually. Then everyone who needs to see things can see them.
In the future, use the group assignments in Classroom versus GitHub.com. Teams map from Classroom to GitHub.com 1:1, but the teams formed on GitHub.com don’t flow back to Classroom.
Let me know if that takes care of your issue.
