Hi Jonny
Phil from the Data Working Group here.

Whilst you have answered a question with a question you have not answered the initial important question.

You are using an editor called YourAppName, which others have used (at least an editor with the same name) 
resulting in breaking existing data. 

What is YourAppName?, did you write it or where did you find it? Is it documented anywhere and why not use josm or iD?
