I have similar confusing results regarding my Italian ancestry. My results show NO southern european / Italian.
I am 90% Central European and 7% Turkish (?Maybe this is where my Italian is showing up - I have no paper on this?)(3% Uncertain)

My grandfather was Italian and g-grandparents were from Ascoli Piceno, which is on the southernmost part of the Marche region, right next to Abruzzo.
