The Taro (Latin "Tarus") is a river in Emilia-Romagna, in northern Italy. It is a tributary of the Po and is 126 km long. It flows almost entirely in the province of Parma, west of the city Parma. The Taro flows into the Po near Gramignazzo, a frazione of the comune of Sissa, north of Parma.
The Taro flows into Gramignazzo a frazione of the comune of Sissa.
This is definitely incorrect because The Taro flows into the Po which is near Gramignazzo, but doesn't flow directly into it. I think it was difficult for the system because it mentioned both names but didn't quite catch on to the meaning.
