Text stuck in 'heading'

The first paragraph in one document is stuck in ‘heading’ with a font size of 26. I can’t cut it or change it. Any ideas?

Try making a blank doc and cut the words and paste and match style in new doc(ie default) and then copy and paste back in original docs

Check and see what the Binder title for the document is. That sounds like you accidentally shoved that first paragraph into the Title field.
