A family of Microsoft word processing software products for creating web, email, and print documents.
The mismatch between the ruler display and the actual indentation for odd pages is a known issue in recent versions of Word. As you have found, reverting to an older version of the software will only help temporarily, because of the automatic updates. However, since it is a display issue, only, the easiest approach is to just ignore it for now. (Of course, if you haven't already done so, report the issue via Help > Feedback.)
