While adding new citations to the above article, the citation numbering has
doubled. I have 37 citations (ref tag elements) and under the references tag, 74
footnotes appear (doubled the footnotes). If one goes to the article history
page and click on the latest article item in the history, then the numbering of
the citations appear fine (the true 37 footnotes appear). I tried reverting to
earlier versions of the article when the citation numbering worked fine,
thinking that it was due to a error on my side, but the earlier versions also
appear with doubled footnote numbering. It seems to be a problem on the server side.
