Country Epicor Retriever Combo Error

I added the Country Epi Retriever combo box to a customization. It is weird because it doesn’t have any properties that show so I cannot rename it and then if I save and close out and clear my cache and reopen it says the Epi Retriever combo box is missing. Has anyone ever run into this. I added the Ship Via Epi Retriever combo box and it is functioning properly.
