The guidelines https://en.numista.com/help/series-110.html mention that the names of different series from an issuer must be different:
For a given issuer, series names should be unique: two different series of the same issuer should not have the same name.
However, there are series with the same name from different issuers, and we have a problem choosing the correct one in the search:
The system should write the name of the issuer near the name of the series, to know what series we want search. A filter of currency was recently added where the name of the issuer is written below the currency to distinguish currencies with the same name. The same could be done with the series.
