Thank you Dominik.

Using 'com.github.pjfanning:xmlbeans:2.6.2' fixes the issue.

    Hi,
    
    You might hit a known bug in XMLBeans, the library that POI currently uses
    for serializing the XML data, see
    https://bz.apache.org/bugzilla/show_bug.cgi?id=54084 and
    https://bz.apache.org/bugzilla/show_bug.cgi?id=59268 for quite some
    discussion on this issues. You may be able to use a beta-version of a newer
    XMLBeans version from
    https://github.com/pjfanning/xmlbeans/releases/tag/2.6.2, we would be
    interested if this also resolves your problem.
    
    Thanks... Dominik.
