Fixed bug: The X-axis label of a Grouped graph returns to showing Column Titles after I choose Row Titles.

You can choose to label the X axis of grouped graphs  with either row labels, column labels, or row numbers. This is a choice in a drop down list in the bottom right of the Format Axis dialog. 

If you save the file in PZFX format (but not PZF format), that setting is lost. When you reopen the file, the labels will revert to column labels. Since the problem only occurs when opening PZFX files, so you can bypass the problem by saving in the PZF format. 

We have fixed this bug in Prism 5.03 and 5.0c.
