Got Black (not Blank) Cards. Normal or not?

[N-TG]

I got the Greek edition of Munchkin 2 and 3 this week and I checked the cards to see if everything are alright and if all the cards are there. But in both expansions I got, from each one, an additional 8 black door cards (Pick of the cards. I posted this on the Munchkin reddit and some people told me that it would be good to let people know to see if there is any problem or anything wrong.


PS: In both expansions all the cards are there and nothing is missing. Also I hope this is the right part of the forum to tell something like that.
