I wouldn't take the address nodes as authoritative for the street name (I imported them and they could be wrong, especially for roads that are part of a route). Instead, I would use local signage from street-level imagery (ground truth) or https://www.maine.gov/mdot/mapviewer/index.html?hide=FFC&show=CSL%20Safety%20Data%20Public (an authority)

But also, t2editme has never responded to comments, so if you think something is wrong, don't wait for them to respond, just fix it.
