Sorry about my "contribution" not made intentionally. Never done any import, so the only thing I can think of is the I had a problem regarding inconsistency between local file and server when uploading. I exited out of JOSM, but maybe those nodes were somehow updated. Tried to fix things after that and that might have added more nodes.
Thanks for yr changes, as I´m not able to do it properly.

I don´t know how to revert this, so can you please do this for me? Thanks.
