Self Employed 401(k)

After putting in my business gross income for the year and checking the Maximize box for my self employed 401(k) contribution, under the SELF EMPLOYED RETIREMENT DEDUCTION page, it says the following: "Using the maximum allowable contribution, Henry can defer a maximum of $27,000 to a 401(k) plan." However, on the YOUR RETIREMENT CONTRIBUTIONS page it say the maximum allowable for qualified plans is $32,000. It also has $0 on the line corresponding to Individual 401(k). Also, on the page with all my business info (income, expenses, etc) on the line for  Self Employed Retirement it has the large number. I am confused. Which amount is the maximum I can put into my 401(k), 27k or 32k? Thanks to anyone who can help.
