Printing labels

[Tom Jones]

I am trying to print some mailing labels.  I have converted my spreadsheet
containing addresses to an .odb database file.  Then I go to
"File>new>labels to open the labels dialog.  When I try to enter the name
of my database, I find that I cannot delete or add anything to the
incorrect choices listed in the dropdown list.  I have closed and restarted
both the Open Office program and the computer, but I still cannot change
these entries.  Any suggestions?
