Spouse / settlement visa application

Hi, my first post here.
I am applying for my wifes UK settlement visa, i am her sponsor .
i have encountered my first stumbling block on my wifes settlement visa.
On the finance section it is asking have i ever received S.D.A, (severe disablement allowance)
This benefit does not exist any more and is now called E.S.A. (employment support allowance) according to google but there is no tick box to say i receive ESA which is a requirement to bypass the working requirements as i am disabled.
Has anyone else encountered this problem
Many thanks for your time and help

problem solved,
just answer and tick the box which applies...dont think to far ahead.
