K12 Autosomal map : East European admixture (from Dodecad)

Doesn't it say on the eupedia website that there is a complete lack autosomal data for the countries Slovakia, Czech republic, Bosnia-Herzegovina, Serbia, and Macedonia? Then this map is not really that accurate at all considering all these countries together make up a huge portion of Eastern Europe. I also don't understand why Northern Russia would be the most Eastern European considering they have a substantial amount of Finno-Ugric y-dna, which must also be in Norther Russians autosomally considering how close they are to Finland.
One reason why Eastern Europe shows up as such a strong cluster in many analyses is probably the spread of Slavic languages and culture. The Slavic family expanded over a very wide area and will affect clustering.
