Hi Richard Cross,
Thank you for contacting Telerik Support. When you get an item that has already been published for editing the state of the item changes, since you're creating a newer version of that item. However this is not a problem, since it is used only to notify when was the last version published and who was its author, when comparing revision versions of the same item. These changes are not reflected in the frontend, where the original publication date and author are preserved.
I hope this information helps. Please let me know if I can assist you any further with this service request. Thank you in advance.
the Telerik team
