Text deletion issue

Testing version: macOS Version 2.0 (11208) - latest testflight build

What were you doing: editing text in note

What feature did you use: editor

What happened: Text in line deleting in one particular circumstance. I have a H4 level header as a numbered list. Under this I add text. Each new line creates a new numbered list (which isn’t a big deal for me really given I’m formatting it differently from the norm). However, if I add a space after a full stop before pressing ‘enter’ to move to next line. The text delete’s itself.

What did you expect to happen: Not delete the text
