Wrong PDF

I just attached the tune Hull from #104 in hymnal Ador1971 to the tune authority "HULL (Chandler)", but when I checked to make sure it was the right tune (which it is) I saw that the PDF proposed is not the right tune, but rather "HULL (Hull)", which is apparently lacking an appropriately names authority of its own. I don't know how to detach a PDF from an authority. http://www.hymnary.org/media/fetch/118649 is the address of the PDF in question.
