Possible bug -- formatting bar always showing

Hey everyone. I have this formatting tool bar stuck at the top of the new DT3 Beta. Is this supposed to be there or a bug? – can’t seem to get rid of it but pretty sure it was not always there.

Replying to myself here…
Found the hide formatting bar in the format menu.

It’s also Shift-Command-F and covered in the built-in Help > Documentation > Documents > Plain and Rich Texts.
