Track Changes problems between LO and MS Word 2007

I can track changes in LO and MS Word 2007, but when I edit a normal docx text file in LO and then open it in MS Word I can’t see my insertions. MS Word shows my insertions as deletions in the track changes bubble. I feel like I’m new to LO so I probably need to set some options somewhere. Any ideas ?

Basically:

Always create and save your files in LibreOffice and save them in ODF format (ODT, ODS, etc.).
Always keep these files as their source. If you need other formats for distribution to partners, you can open an ODF file and save and distribute another format with ″ Save as… ″.

This way, you always have working files available in your system environment.
