I think there is a problem there.

Can you be more specific please, don't see a problem on our end.

When I sort the UFA by "Age", the "true" UFA disappear (ex.: Vrbata, Hudler, Tanguay, etc.) and only those who signed in Europe or retired appear (ex.: Versteeg, Phillips, Medvedev, etc.)

Thanks for pointing this out, Should be fixed now.
