Polish coins from 65th Anniversary of the Warsaw Uprising - Warsaw-born Poets - inproper composition [Risolto]

Hello, couple of days ago I bought these 2 coins:

10 zł Kamil Baczyński - https://en.numista.com/catalogue/pieces28820.html
10 zł Tadeusz Gajcy - https://en.numista.com/catalogue/pieces28819.html

Both of them are in fact same composition, yet in Numista catalog they are described differently.

10 zł Kamil Baczyński's composition is described as "Gold (.999) plated silver (.925)" (plated outer ring) and therefore it's bullion value can be calculated. This is basically ok.

On the other hand 10 zł Tadeusz Gajcy's composition is described as "Bimetallic: gold (.999) plated silver (.925) center in silver ring" which is utterly wrong, because it is not bimetalic - only gold plated in the center of the coin. Composition of this coin is basically the same as for 10 zł Kamil Baczyński coin, with this small difference of the gold plating placement. Therefore for this coin no bullion value is calculated.

10 zł Tadeusz Gajcy's composition should be changed for Gold (.999) plated silver (.925) with description "with plated center".

I tried multiple times to change it via "Modify or add data on this page", but with no effect.

Here are the official information provided by Polish National Bank: https://www.nbp.pl/homen.aspx?f=/en/banknoty/kolekcjonerskie/2009.html

So they are out of to different metal rings, they might be the same composition but bimetallic is how we categorize such coins.

Ok, but I still don't understand, why one coin is listed as single plated metal and another is listed as bimetal, since both of them are in the same set and basiclly same composition, with the only difference in gold plating placement.

And I also don't understand, why bimetal coins don't have bullion value calculated, when their core is composed of precious metal.

Is there a specific reason for that?

EDIT: I don't mean disrespectful, but I'm very confused of why this is so inconsistent in this case, that's all ;)
