In Polish, the word "Name" has several meanings.
Usual "Name" is translated to "Nazwa",
"Name" in the sense of "first name" is translated as "Imi?",
"Name" in the sense of "last name" is translated as "Nazwisko".
In other languages ??the situation may be similar.

Solution is simple.

Then I added the correct translation for this context.
