Comment 6 for bug 1880395

It works for me.

Steps I did to try it:
1) right click on authors in the tag browser
2) select Manage Authors
3) Click the button "Copy all author sort values to author"

at this point several authors show the "quill" icon indicating they have been changed.

4) press OK

The authors with the "quill" are updated in the book list.

I also tried it from "Edit Metadata - Single". It took a few seconds for the edit metadata screen to update, and the change was made in the database.

What are you doing that is different from the above?
