When filtering by rarety the system for instance this is happening.

Act of Treason M12 Common.

This card displays when i have my filter set for M12 Red Uncommons. This I looked at the further details of the card and it WAS an uncommon in M10 and then common in M11 and M12.

I also use the card details to enter what version of the card i have and the system is not smart enough to override the card detail with the other detail.

Little help. Thanks :)
