How to get rid off this white space in the header?

I safe news article as RTFs. The preview in the database shows a very large white space, that’s not nice. It’s not there when I open the document in TextEdit. See the Screenshot please.

Did you enable typewrite-like scrolling?

Yes, I guess. Will disable it and see.

Okay, that worked. Looks fine now.
