In my 2017 Subaru Impreza, how can I delete an entry?

I have a 2017 Subaru Impreza that I bought as a used car. The dealer showed me how to delete the previous owner's entries. However, I am unable to delete the single entry I in-puted and the dealer does not know how to delete this one item. I live in the London, Ontario area and there is only one dealer in town.

Help, please.
