Hello,

I'm experiencing something weird with some of the titles in the series info page not being the main title, this seems to concern about 1/3rd of the works. Here are a few examples

https://www.mangaupdates.com/series.html?id=121092 shown as "Aşk Bir Otaku İçin Zordur"
https://www.mangaupdates.com/series.html?id=161 as "Ayın Son Çeyreği"
https://www.mangaupdates.com/series.html?id=152384 as "Akamatsu (et) Seven Les colocs d'enfer ! (french)"
https://www.mangaupdates.com/series.html?id=118883 as "Apari3ncias"

Here's a screenshot: https://imgur.com/MxqgF6l

There's no consistency in the language being shown and when I open the manga's page, the right title is shown at the top of the page. I tried looking for a language setting in the user CP but there doesn't seem to be one.

The page you're looking at will show every name (including Associated Name) for every series. You're specifically looking at the A's, so it will show every main name and associated name that begins with A. Notice in your screenshot that every series name there is in italics. The italic font indicates that it is an associated name. A non-italicized name would indicate it is the main name

A just ruler amongst tyrants

Ah thank you for the answer, that is an interesting feature!
