I tried to sort alphabetically (ascending) and the program crashed. It crashed each time I tried to do this.
On which env are you (Windows, Linux, MacOs)? Which LO version do you use? Do you reproduce this on a brand new file?
I'll quote reporter's comment: " Windows. Sorry I do not know what version. When I created a new document it worked just fine. I went back to the original document and re-tried the sort and it worked just fine. Thank you so much for your email and your willingness to help!!! " Deb: to respond to emails sent by bugzilla-daemon@freedesktop.org, please use don't answer directly from your emailer but by clicking on this link: https://bugs.freedesktop.org/show_bug.cgi?id=87201# BTW, to know your LO ("LibreOffice") version, just click on "Help" menu, then "About LibreOffice". Anyway, following your comment, I put this tracker to "WorksForMe".
