In my Profile Stats it shows that I have finds in 3 regions of Spain:
|Islas Baleares: 17||Andalucía: 9||Balearic Islands: 5|
Actually it should be only 2 as 'Islas Baleares' and 'Balearic Islands' is the same.
You can also see this bug in the Map Regions tool. In the text area below the map it will show two entries for the Balearic region but on the map, if you hover the mouse cursor over this region, there is only 'Islas Baleares'.
In my opinion this might be a translation issue and it should be named only 'Islas Baleares' similar to 'Islas Canaris' (which is correctly listed only once btw).
