Hi, 
I noticed that this street is tagged as:
name=вулиця Сидора Голубовича
name:uk=вулиця Сидора Голубовича
name:en=Sydora Holubovycha Street
name:ru=Сидора Голубовича улица
name:pl=ulica Niemcewicza

It seems that the Polish name does not correspond to the others.

Could you please confirm whether “ulica Niemcewicza” reflects an official local name or if it might have been added by mistake?
