how to remove hyperlink in openoffice writer

Whilst they have kindly provided me with a 'fixed' version of the pdf, I would like to know how to find and remove the hyperlink from the original document, preferably without losing any formatting, so that I won't have the same problem with future revisions (especially given that this is still only the first proof reading edition). However, when I exported this as a pdf and uploaded it to Lulu, again they refused to print it on the basis of an embedded hyperlink. Theoretically this should have removed hyperlinks from the entire document. If you have them in there, remove them or start a new document that doesnt. Then I selected the entire document, by pressing Ctrl-A and then right-clicked and selected Remove hyperlink. This new document should not have any headers, footers or page numbers turned on. So I went into the autocorrect options, deselected the two checkboxes for 'hyperlinks', so that it wouldn't create any more. However my first attempt to purchase a proof copy ran into problems as the pdf apparently contained 'hyperlinks'. I have followed the instructions for pdf export that lulu have given for OpenOffice (given that LibreOffice was originally forked from OpenOffice and the pdf export dialogues still have the same tabs and much of the same options). I have a small book in LibreOffice writer format that I am preparing for self-publishing on Lulu.
