This question is unfortunately incomplete and hard to answer. Please be more specific.
Also it seems you want to report a bug in LibreOffice in combination with Unity. If that is the case, please file a bug (with specific information on what you think goes wrong) here:
Addendum: If you want the experimental global menubar integration for LibreOffice, please install the package lo-menubar.
I think he means the following problem: There is no proper integration to the dash-bar of Unity. The general LibO-icon is visible whereas the writer-icon is not visible…?!
Edit:But his question could refer to another problem with unity…
I think there has to be some more work going into Unity integration of LibreOffice
