Level 1 Model Building: Employee List won't import Start and End Dates



I am on module 1 of the Anaplan training, and when I upload the #E2 Employee List, Anaplan won't pull the start and end dates. I didn't catch that until I got to the creation of SYS08, where #E2 is referenced, but the information won't load to the module, as the start and end dates aren't on the original list. Can you please help?
