Part time maintenance loan query

Undergrad course, 4 years studying part time over 8 years, applying for finance for year 3 (of 8) - SFE application does not ask about course intensity (which is 50%) and advise maximum maintenance loan is £2495, SFE calculator advises it is £6501. Divorced, no partner, 15k income pa, under 60 on day the course originally started (although over 60 now). Why does application limit maintenance loan to 2495?
