Hi,

You keep on removing tratto and similar street name prefixes and suffixes to street names as shown on signs ON THE GROUND, which is what we map. Truly can't care what ANNCSU or the tax office says it is. If it is different from ON THE GROUND, then you can tag it under official_name 
(751000 uses world wide) or alt_name. https://wiki.openstreetmap.org/wiki/Key%3Aofficial_name

At any rate, there's no conflict ON THE GROUND, so I'm going to revert to what's shown on the corner sign.

cheers
