Why is the Schedule by Person view not reflecting assignments?

[Janene Pappas]

I have a Plan set up for a team, all team members have been added and I've put a few assignments to individuals. When I look at the Plan grouped by person, the assignments are not reflected at all and issues are shown under other team members. How do I get this view to reflect actual workloads? Below, all "MyCardRules" issues are assigned to Maria and all "Zelle send money" issues to Nathan. The other team members should have no assignments.

I've figured this out. A combination of correct Import settings and using the Calculate button.
