Duplicated System Architect Mission

In my dashboard, I selected a System Architect mission, but I saw another one with the same name, different hours, and different modules.

Which one is newer? What’s the difference between them?

One of the mission is for PEga Version 8.4 and the other one is for Pega 24.2. The latest one will be Pega 24.2 since it will also includes AI enhancements and other new features in the course modules.
