I've imported a document from Word. I have a problem removing the imported page numbers and adding mine. This is what I got:

The rightmost "6" is the one coming from Word. I can't get to select it (in order to delete it). The other 6 is the one I added as page number, but I don't know how to move the containing box upward.
Any help?
