Hidden Edge?

Hi,
I’m making a building, and need to do some loop cuts in order to do a floor plan, and the face of the floor is not there. When I fill in the four vertices, it says the vertices already make up a face. When I lift up the whole thing in edit mode, the floor isn’t there, but when I do lift it up in object mode, the floor is there. Is it hidden, if so, how would I make it ‘unhidden’

Thanks
