When i type add spaces at the beggining of a line and a dash after it libreoffice removes the spaces. For example i type: - EXAMPLE and after i press enter libreoffice changes it to: - EXAMPLE
That's not a bug, but the result of preference Men 'Tools -> Auto Correct -> Options -> Delete spaces and tabs at beginning and end of paragraph -> [T]=checked' That will replace spaces left from "*", "-" and "looks like numbering".
