I think this sequence of screenshots will do most of the explaining. The first screenshot shows the issue: the Projects page doesn’t list anything. The second screenshot is after I hit the “Add Project” button. The page shows projects that have already been added, including the first one which is part of the “StreakYC” org I was just viewing in the projects page. The third screenshot is after I clicked its link to show that it’s part of the “StreakYC” org.
The Projects page has an org-picker at the top left. If I pick my personal account from that list, it correctly shows the projects added from my own account. The buttons for the two orgs I’m in both lead to an incorrect “$org has no projects building on CircleCI” page.
