[RC6 HDPI] Line spacing not persisted when closing and reopening a project


I am using the latest version, RC6 High DPI Version, and I set the Default Formatting line spacing to 1.5 lines. Everything seems fine when I edit and save the project. When I reopen the project, the line spacing setting is lost. If I go to Document->Convert to Default Formatting it works again, but if I save, close and reopen the project, the setting is lost again.
