Example file from Calc with pivot table

When creating a pivot table and trying to change the data field sort order, the order is not changed unless a different sort criteria is selected too.


Steps to reproduce:
    1. Create a simple data table, 3x3 in Calc
    2. Select all the data and create a pivot table from it
    3. Set two columns (Year and Sales in my example) of the three as Row Fields in the Pivot Table Layout Window and the third as Data Fields
    4. Double click on the first row field (Year in my example). The Data Field window opens.
    5. Click Options in the Data Field window
    6. Next to the Sort by dropdown, select Descending instead of the default Ascending. Do not select the Manual option, that one seems to work :).
    7. Close the Data Field Options window by clicking OK and the Data Field window too.
    8. Reopen the Data Field and Data Field Options window. Notice that the sorting order is still Ascending, despite the former selection.
    9. Now in the Sort by dropdown select a different option (Sum – Expenses in my example) and select the Descending option.
    10. Close the Data Field Options window by clicking OK and the Data Field window too.
    11. Reopen the Data Field and Data Field Options window. Notice that the sorting order is now changed to Descending.


Actual results:
The sort order is not changed from Ascending to Descending (or vice versa) without changing the row field used for sorting.

Expected results:
The sort order should be changed without changing the row field used for sorting.
