When searching for a language which is present in many regions (e.g., English or Spanish), this single language appears many times repeated.

When several languages appear in the results, having some languages repeated in different regions is not a problem. But having a single result which is repeated multiple times users may think there are different options to chose from.

This situation may be avoided if when the user searches (and only during search) either (a) repeated languages are only shown on the WW region, (b) it is avoided to show regions with only one language if their languages are already in another region, or (c)languages in search results are not grouped by region if there are only few results (e.g., eight or less).
