Hi Dom,
The reason why you see two status in the content deployment, maybe it's related to an ConfigMgr upgrade that you did before and the content was changed once you have promoted the pre-production client to prod.
You can also compare the creation date of the content status with installation of in-console upgrade packages under Administration >> Updates and Servicing node.
