Story Editor text gone after save or exit

[garryc]

Fedora 34, Scribus 1.5.6.1. I have used Scribus for many years. I use it for my club magazine. When I go into Story Editor to change text size or colour etc. then when I save or ctl/W the highlighted text has disappeared from the text frame. This was not a problem before the 1.5.6.1 update.

I downloaded Scribus 1.5.7, Story editor now works
