Hi there, sorry this has been an issue for you. Can I just confirm this is the behaviour you mean?
When I put hyphen at the start of the sentence, it becomes a bullet point. In the middle of the sentence it seems to work fine (both examples in the screenshot below)

Weird. For me nothing happens, when I type in a hyphen. I recorded the workflow for you to understand better: https://scribehow.com/shared/Shopia_Hyphen_problem__K0RUSgCeRiad3xAumiaBaQ

I can't type a hyphen either
