Same goes for bullet list. And interestingly, if I have a checklist already and make a new line (which is then formatted as a checklist) and try to make it into a bullet with the key command, it then becomes regular text (neither checklist nor bullet).
Looks like that is a bug, indeed. We will fix it and get a fix out soon. In the meantime, a way to make a checklist or bullet list is to begin the line with [] or -, and follow by space and then the text.
