Need to restrict the Address Data as its duplicating a single City LOV in multiple languages

Hello Everyone,

I need a solution for the Supplier Address Data restriction, we are getting duplicate values for the same city in different languages.

Even if we filter by languages, still we get multiple entries. Client is having trouble to choose the LOV value.

We know we need to use Manage Geographies related tasks, but need some elaborative steps on that or a document would help.

Thank you,
