How can an employee see more than 9 delegations in My Team > My Team dropdown list?

Summary: We have an employee who has more than 9 line manager delegations, but in the drop down list of assignments/delegations in My Team > My Team she can only see a total of 10 (her assignment, plus 9 delegations). There isn't a way to expand the dropdown or type in additional names.

Content (required): As recently as Dec 2021, she could see all delegations to be able to do her work efficiently. We need to be able to have a scroll capability or some other way to see her full list of delegations.
