UK Home Office - Form confusion!

Hello,

I’ve started to fill out my Stage 1 application form via Home Office website and I’m confused about 2 sections:

  1. Position Applied For: It’s seems to be asking for job offer but I already have a job as I live and work in the UK. Should I check ‘Yes’ or ‘No’ ?

  2. Letter of Endorsement: For the endorsement letter section, it is asking for ‘Further details’ - What goes in this box. It’s not the letter content is it ?

Appreciate any and all advise very much.
