Cities with the same name using GeoCharts

I'm doing a project, using GeoCharts, how I'm working all the municipalities all over Brazil, there are some cities with the same name, when I show these cities, they appear in the wrong state, has anyone ever had this problem? In the following picture, I am searching all the cities of the state of Pernambuco, and I checked the cities that are in another state, are the ones that have the same name, example in RS.
