In exchanges for each collector there is option "My wishes", there you can set what do you wish and what not.
Under coins type I set there that I don't collect "Non-circulating coin".
Shouldn't that be also taken in cosideration in swap filter under "See XcollectorX's coins to exchange"? Currently I see also those coins I don't want... :(
If you make like Grinya suggest then you don't see particular coins you marked in "Individually selected coins of your "don't wish" list" and those coins aren't visible:
I'm speaking about setting in "List of coins I don't wish" in "My swap wishes":
As you can see there is marked "Non-circulating coin" but I still can se those coins in list of coins from other collector... :(
