attachment 152514 [details] compare MSO 2016 LO 6.4+.jpg
Last cross referenced text from DOC saved in LO is visible in LO but not in MSO.
Confirmed with LO 6.4+.
Open LO created DOC such as attachment 152514 [details] and see a difference.
Screenshot comparison for that DOC attached.

1. In LO open ODT with cross references like attached sample
2. Save as DOC and close
3. Open in LO and MSO and see last cross referenced text missing in MSO
Looks inherited from OO.
