Example file made with Word 2016

If we create a simple Bar Chart in Microsoft Word 2016 and we set two column for X category axis, in that case in Microsoft Office Word two category label will appear on the X axis. If we open the same document in LibreOffice Writer the labels disappear from the chart and also from the Data Table.

Steps to reproduce:
1. Create a new document in Microsoft Word.
2. Click on Insert, and add a chart to the document.
3. Choose the Stacked Bar Chart and click OK.
4. Insert a new column in front of ‘Column A’ in the pop-up excel spreadsheet.
5. Enter a new value in ‘A2’ cell. (Do not need modify the default data on other cells).
6. Modify the category axis label at “Select data” and select the first two column (=Munka1!$A$2:$B$5). Click OK.
7. Save the file as DOCX and open it with LibreOffice Writer.

Actual results:
The X category axis label disappears from the chart and the data disappears from the Data Table.

Expected results:
The X category axis label and the data in the Data Table should be preserved.
