title: Word field definition issue after save
body: <p>I have field definition in Word 2016 (Office 365 same problem) like this</p>
  <pre><code>                    &lt;w:r&gt;
                          &lt;w:fldChar w:fldCharType=&quot;begin&quot;/&gt;
                          &lt;w:instrText xml:space=&quot;preserve&quot;&gt; DOCPROPERTY &quot;UohsDate&quot; \* MERGEFORMAT &lt;/w:instrText&gt;
                          &lt;w:fldChar w:fldCharType=&quot;separate&quot;/&gt;
                      &lt;/w:r&gt;
  </code></pre>
  <p>after filling field by docx4j, editing document in word and saving document again, my field definition is divided into two:</p>
  <pre><code>                    &lt;w:r&gt;
                          &lt;w:instrText xml:space=&quot;preserve&quot;&gt; DOCPROPERTY &quot;UohsDa&lt;/w:instrText&gt;
                      &lt;/w:r&gt;
                      &lt;w:r&gt;
                          &lt;w:instrText xml:space=&quot;preserve&quot;&gt;te&quot; \* MERGEFORMAT &lt;/w:instrText&gt;
                      &lt;/w:r&gt;
                      &lt;w:r&gt;
                          &lt;w:fldChar w:fldCharType=&quot;separate&quot;/&gt;
                      &lt;/w:r&gt;
  </code></pre>
  <p>Please, any suggestions? Thanks a lot</p>
