Required field

[AgileHappyLearner]

Two issues, same issue type, same workflow schema, same workflow, I could close one of them and can't close the other, I receive a message indicating that I cannot close it because a field needs to be completed but it is a field that is not configured for this type of incident and I have closed many others without it. I have already looked at the workflow in detail and it does not have any validator configured that requests the field for that type of incident, could you give me any clue where else to look?
