I decided to apply the 10.0.2 patch and I believe it has succeeded; as the registry key updated, inventory module updated, and the Status Details for the System Update Status lists the patch as Successful :2 (1 server and 1 workstation).

However, when I browse to these devices in ZCC and refresh their Upcoming Events, the 58 Deploy entries are still listed.

When do these clean up? Am I supposed to do something manually? Or does the system eventually remove these events?
