The option "Don't add space between paragraphs of the same the same style" it is not showed when editing styles, it is only visible with direct paragraph editing in the text.
Creating a style from selection, preserve the option even it is not showed in the style box editor.
The attached file has a style with the option on. (DontAddSpaceBetweenParagraphs)
F11, select the above style, modify, the option is no visible.
Select default style and write a text, verify with right-click/paragraph the option is off.
Apply the DontAddSpaceBetweenParagraphs style to the text, verify with right-click/paragraph the option is on.
Thanks for the bug report and the workaround! Using AutoUpdate of Organizer page of the styles is also a workaround for this bug.
