Another Issue with MusicXML Export

I think this is a serious Issue. I have exported my midi track to MusicXML, however, when I opened it in finally ( after saving opening it in textedit and saving it of course!!). All the chords are wrong ( no chord inversion) and if I have two chords in a measure, they are jammed together at the beginning of each measure. Here is another user reporting issue with chords, however mine is different. Please see the attached file.

Any one knows how to fix this please?

Thank you.
