Above the Sources section:
Inline citations should look like <ref>some source listed here</ref>
they can be named, so <ref name="foo">bar</ref>
and then reused like so: <ref name="foo" />
In the Sources section:
there should be a <references /> tag, which triggers the code to display all those inline citations that were above it.
there should not be any <ref>foobar</ref> inline citations after the <references /> tag. If you find those you can:
1. move them to the right location in the bio if you see where they belong, and make them inline citations
2. take the <ref> </ref> tags out but leave the text, and add an asterisk (if it's not already there) so that it appears as a bulleted Source
Make sure you leave "Data Doctor Suggestion <whatever number>" and an explanation in the comment for your change, and then also change the Status of the suggestion with a comment, so others know it's fixed.
