"Year of Publication" input box appears to have the wrong name

The "Year of Publication" input box appears to have the wrong "name".
It seems to be confused with the biblio_other_author_affiliations input box.

The HTML output is:

<label for="edit-biblio-other-author-affiliations">
Year of Publication:
<span class="form-required" title="This field is required.">*</span>
</label>
<input type="text" class="form-text required" value="1234" size="60" id="edit-biblio-other-author-affiliations" name="biblio_other_author_affiliations" maxlength="255"/>
