The disclaimer you have in the body of the chapter is more than sufficient. We've allowed disclaimers in the body of the chapter when the disclaimer will cover more than the 240 characters allowed by that field, and the notation to see Chapter 1 in the disclaimer field is also acceptable.
The simpler disclaimer in the field, as you have it now, is more than sufficient for our purposes, but the more comprehensive one in the body of the text was not incorrect. I'll update the records to reflect that this was correct.
