Pip review questions query?

Hello all I have a pip review letter which initially gave me 7 days to return! Got an extension and told me just to fill in no change if that was the case.. I am photocopying all my supporting letters from 2019 and will update. GP has provided a letter for supporting my on going claim. Also using the original info I provided but updated and on separate sheets with NI Etc My question is, in the descriptors that I didn't get any points for .. On my original form I filled it all in except for the ones which weren't applicable. Should I fill them in with all the original information or leave them to no change? I have concentrated on the descriptors that apply to my original claim. I felt the answers given by the health visitor were fair and I am happy with the award that was granted, and so fingers crossed I am hoping for the reward to continue as was. I am on high rate mobility and low rate care. I filled in pip form in 2019 purely with the help of this group and guides, so doing the same. Thank you

Thank you for responding Your advice would be to fill in the sections with extra info even though they are not part of my reward ie planning journeys that I went I to detail with originally but go 0 points which in all honesty was probably fair?
Thanks
