It's pretty clear to me ITALIAN score on 23andme/AncestryDNA is related to J2, while BALKAN score on 23andme is related to E-V13, as I see this pattern in all my matches. Now I do not understand why you can't understand how admixture can change in 1400 years, but if you believe that nothing has changed, I will just have to wait for ancient samples from correct time periods to shut you up.
