Calibre puts in <dc:contributor id="id-6"/>

[Robert Fisher]

Calibre keeps putting in this line and its accompanying line.
<dc:contributor id="id-6"/>
<opf:meta property="role" refines="#id-6" scheme="marc:relators">bkp</opf:meta>

<dc:contributor id="id-6"/> fails epub checker and I figured out why
The line should be <dc:contributor id="id-6">String length of at least 1</dc:contributor>

If I fix that line like that, then Calibre would put in
<dc:contributor id="id-7"/> and
<opf:meta property="role" refines="#id-7" scheme="marc:relators">bkp</opf:meta>

If I delete those two lines, save, close the editor, and reopen the editor they magically return.

The work around would be to get as far as I can, then open the epub file manually and remove the lines, but as soon as I have to go back into Calibre, it will put the lines in and that means epub checker failure.
