Hi Bill,
Thanks for your update in private message.
From the screenshot you provided, I can see the tasks that are not showing up on Planner Schedule window belongs to a created Planner tab within Microsoft Teams. I'd like to explain this is an expected behavior.
The Planner tab in Microsoft teams and Planner (tasks.office.com) aren't the same thing. When adding a Planner tab in Microsoft Teams, it means we can create new tasks in Planner (Tasks.office.com) through Microsoft Teams. Task owners can see the tasks assigned to them under My tasks section in Planner (tasks.office.com), but the tasks created under Planner tab in Microsoft Teams will not appear in associated plan in Planner (tasks.office.com), that is why you can't see those tasks on Schedule window in Planner.
