Mixes: Crying Wolf (Hungary)

[Tyaleka]

I was wondering how it is possible for a dog to have this symbol (_!_) against its name when the parents do not. Also how is it possible for 1 of the litter to have it when litter mates do not? as an example, I was looking at........
Moňa z Krotkovského dvora CS (_!_), her parents are not (_!_)

Fallko Kollárov dvor (_!_) , his parents are not (_!_)

Looking at the parents of the above dogs offspring there are the only 1 in litter to have this mark against their name, how is this possible when all in litter have the same parents.

Thank you in advance for any helpful reply.

Just purely conjecture, but I think perhaps the "!" means that the dog or bitch may be listed on the pedigree officially as the parents of some puppies but there are some reasons to believe it may not be so (like some strange puppies in some litters, or the kennel is known for having bred mixes with fake pedigrees, or so)?
