Performing the first Challenge of this Superbadge for APEX, I am receiving the below error. But it is not true because the Maintenance Request does indeed have all of the attributes cited when I try via the GUI and via a Test Class. Can someone please tell me what is wrong?

Challenge Not yet complete... here's what's wrong:
Inserting a new Maintenance Request of type 'Routine Maintenance' and then closing it did not create of a new Maintenance Request based upon the original record correctly. The challenge is expecting to find the closed Maintenance Request plus an 'New' Maintenance Request of type 'Routine Maintenance' with the same Vehicle as the closed one.

(Also, the challenge didn't specifically mention that the Case and Product2 objects should be relabeled)
