The series page now displays the issuers that can use the series. And this is fine.
But we have series shared by two or more issuers that are really different series, each one with its issuer, issuing entity and mint. But they were joined when the series were converted into entities. https://en.numista.com/forum/topic122633.html#p1200099
Now it is difficult the detect in the series page, because we do not see the issuing entities and mints of all its objects. We need search for the objects in the series and filter by issuer trying to find clues in the object pages that say an object is part of a different series.
For example, these series related with Chinese calendar has many issuers:

https://en.numista.com/catalogue/series.php?id=2600
https://en.numista.com/catalogue/series.php?id=2602
https://en.numista.com/catalogue/series.php?id=2572
https://en.numista.com/catalogue/series.php?id=3040
https://en.numista.com/catalogue/series.php?id=5431
I managed to detect and split some series with their issuers, but seeing the issuing entities and mints in the series page would be helpful.
Additionally, displaying the issuing entities and mints of its objects in the series page will give more information to the user, without need add this in its description.
At first, this data could be provided via code, without any database changes: when a user visits a series page, the system searches for issuing entities and mints in its objects, and displays the information found.
Later, if this is resources intensive, the issuing entities and mints of a series could be saved in the database, just as the issuers are saved now.
