All fixed now, I think.
More information: The "ref name" format only works in WikiTree if the first instance of the citation is a full citation (e.g., <ref name=Hobart>"The Hobart Journal."</ref>), not just an abbreviated version like <ref name=Hobart/>.
Fortunately, if you repeat the full citation later in the profile, the reference list will still group all of the citations of that name together. When I am using the ref name format, I often insert the full citation every place in the profile where I expect to use it. That way, when I change my mind and rearrange the text, the citations won't be lost.
