Most of her filmography was made in Italy under "artistic" name Susanna Martinkova, which is most likely why this name is locked (I don't remember locking her name and I usually lock only names of Czech actors confirmed by filmovyprehled.cz, but I can't deny it could as well be me who locked it ). Here is the respective rule from our Contribution Bible:

Name

The primary stage name someone uses.

Many actors (and non-actors) use multiple stage names in their career. When a name change is linear, you should use the last name used by a living person. For example, Caitlyn Jenner, or Alexa PenaVega rather than Alexa Vega.

When a person uses many names simultaneously and alternatively, choosing a primary name is usually a judgment call based on a few factors: Is there a name they are most often credited as? Which name is used on their official website and social accounts? Which name is used on their agent or union's website? Which name are the other major websites are using?
...

Well yes, part of her career was in italy - and not all movies have that edited name. Since then she star in slovak movies/tv shows (like quite recent https://www.themoviedb.org/tv/88353-autoskola) with her birth name... not pseudonym that she used only in some of her italy movies. Since she star in cz/svk production now and also she tell her name in interviews - her primary stage name is "Zuzana Martinková" as i said before ;)

OK, you'right. I've unlocked the name field.
