there seem to be some duplicate primary ways. I’m guessing that whatever there is on the ground there, it’s not quite like that.
I tried asking if they wanted any help in an earlier changeset discussion comment (in English, so it’s not entirely surprising that I didn’t get a reply).
Perhaps someone could pass on an offer of help in their own language?
