@guigui3000 I've used LibreOffice Writer to write my last 3 books. It + Zotero = chef's kiss!
I do notice compatibility issues with Word users, including the issues you've seen. Typically if I collaborate with someone, I get them to agree to avoid track changes, partly because I cannot stand TC -- it just becomes noise. I prefer to have a collaborator and I use labeled drafts/revisions.
