Zarečča is NOT a village. At least not on this place. See for yourself on Mapillary images! This is part of the Narbuty village.
This wouldn't be the 1st time BY database is wrong about the position of a village. 
If we refer tp pre-war maps, Zarečča (Zarzecze) is placed Southeast of Župrany, on the road to Zamasciany (Zamościany). Please check that!
