New German State requested: BIrkenfeld [Risolto]

Can I talk someone into adding "Birkenfeld, Principality of" please?

The Krause "German States" catalog 1601-Present, 2nd Edition dated 1998, which I have, lists about 13 unique KM#'d coins for this issuing authority, including the one coin I own. It's in NGC here:

Text from the Krause manual includes this excerpt:

Birkenfeld: Located in southwest Germany. For most of the time prior to 1801, Birkenfeld was in the possession of the Counts Palatine. It was a part of France from 1801-1814, Prussia from 1814-1817, and was made a principality in 1817 and given to the duke of Oldenburg.
Rulers:
Georg Wilhelm von der Pfalz, 1609-1669
Karl Otto von der Pfalz, 1669-1671
Paul Friedrich August (of Oldenburg), 1829-1853
Nikolaus Friedrich Peter (of Oldenburg), 1853-1900

Already in, not sure why I cannot seem to find them when I search for Birkenfeld under issuers

It works on my side...

Not when you search it this way

which is something to fix in future I believe

Asked mod to move.

Hello,
Typing "Birkenfeld" now returns "Oldenburg-Birkenfeld, Principality of" and "Pfalz-Birkenfeld-Zweibrücken, Duchy of". The same also applies for all compound country names.

Fantastic, thank you Xavier
