Google Shopping Feed has Extra Lines at Top of File

I don't know if it was new, but disabling an Item that I don't think was needed did solve the problem. let me buy you a beer.

rough app adding the lines? Did you check if any new items got added to the template? Just asking :P

Just as it says in the title, a google shopping feed suddenly has started to show 3 extra lines before the header of the file.
This is a non-encoded, tab delimited text file that previously (like a couple of weeks ago) didn't not have these extra lines.
Not sure how any template change could render those extra lines since the 'header' template is simply a line of text.
