Bug — Classes don't show after going back to Schedule Page

[sophiachen646]

Describe the bug
The classes on the schedule don't show up after going to any other page until you deselect and reselect at least one of the courses on the schedule but the classes are still in the Selected Courses section.

To Reproduce
Steps to reproduce the behavior:

1. Navigate to the Schedule Page.
2. Select two classes (e.g. ADMN-1010 and ADMN-1824).
3. Navigate to the Explore Page.
4. Go back to the Schedule Page.

Expected behavior
After having selected courses and going to another page, the schedule should still show up after going back to the Schedule Page. However, you can only view the Schedule again after you deselect one of the classes and reselect it again.
