Description:
- Attached .docx document includes a simple DocProperty "Test" (filled with text value "ThisIsJustAString")
 - This DocProperty is inserted into the document as conditional text/field via:
{IF {DOCPROPERTY Test \*MERGEFORMAT}<>"" {DOCPROPERTY Test \*MERGEFORMAT}}
 - If this document is opened in current LibreOffice versions the field/DocProperty is initially shown correctly
 - If this field is updated (either explicitly via "Update Field" or "Update All") the DocProperty is lost/no longer printed. (Therefore, the DocProperty will also not be included while exporting the document to PDF)
 - If the attached document is saved as .doc (via Microsoft Office) and opened via LibreOffice Writer the DocProperty will never be shown

Additional Information:
If the attached document is opened with earlier versions of LibreOffice Writer (24.8.7 or earlier) the DocProperty was written/shown 3 times. “Update selected field” does not change anything but “Update All” will show the DocProperty afterwards only twice. 


Steps to Reproduce:
1. Open attached documents via LibreOffice Writer
2. DocProperty "Test" is shown
3. Update the conditional field -> DocProperty is not shown any longer
4. Alternatively export the document to PDF and the DocProperty is no longer visible

Actual Results:
DocProperty "Test" is not shown any longer after refreshing or exporting to PDF

Expected Results:
DocProperty is shown/included as the condition defines and is not lost after refreshing the field or exporting the document to PDF


Reproducible: Always


User Profile Reset: No

Additional Info:
see above - in older versions the DocProperty was written 3 times and shortened after updating all fields.
