'Villages' in the Bible

The army of the tribe of Manasseh did not conquer Beth-shean and its villages, Taanach and its villages, the inhabitants of Dor and its villages, the inhabitants of Ibleam and its villages, and the inhabitants of Megiddo and its villages. Instead, the Canaanites continued to live in that land.

When Israel was living in Heshbon and its surrounding villages, in Aroer and its surrounding villages, and in all the cities that line the banks of the Arnon River these past three hundred years, why didn't you retake them during that time?
