Hello,
I just fixed the first issue you reported and changed some texts to accommodate for both coins and banknotes.
I'm not sure I understand correctly your second point. I guess you are referring to this page:
https://en.numista.com/souhaits/liste_veux.php?wish=1
This page lists only the coins and banknotes you selected individually, not those which were selected via the criteria.
If you want to search all your wished banknotes (including banknotes individually selected and the banknotes selected by your wish criteria), you may go to "Catalogue > Search Banknotes", open the search "Options", select "My wishlist: wished" and click on "Search".
