I have an issue with the 'browse author' option for my journal. I found an old forum posting that might be related but it was last updated in 2008.
I just uploaded multiple issues using the XML import tool. I immediately went to see what the issues looked like. While looking, I clicked on the 'browse authors' link. When browsing authors, many of them are listed twice but when clicked, they show the exact same information (they list the same papers and link to the same paper ids, etc).
For example, if I browse by author and click on "D" I get a list of authors as shown here https://journals.tdl.org/absel/index.ph ... hInitial=D
Note that 'Deguchi, Hiroshi' and 'Dunway, Mary M.' are listed twice. If you click on either name for Deguchi, you get the same exact listing of publications (in fact, the URL for each link is identical as well).
I noticed that this only occurred for authors that have multiple articles published in the journal. If you click on any of the non-duplicated name-links, you will notice that they all only list a single article under their name.
To test this, I created a test article for Dunway. Originally there was only one listing for her via the author browse. I went and create a test article for her, uploading it via the quicksubmit plugin. You'll note that there is now two listings for her and both listing list the same two articles.
