The survey would NOT recognize my answer for the first question (personal use) and would not let me submit it - I had to select the “clients” one as well in order to submit. This is going to give you the wrong answers.
ALSO: Selecting N/A on the order of importance RESETS THE NUMBERS! Really annoying to have it all undone with the click of a mouse.
I had the same problems, but then I realised that the questions were to be answered in importance to you personally. In other words, the one that is most important, select 1, next important - 2, and those that are not applicable to you, select 'not applicable, which will reduce the numbers available for the rest.
Curious if they actually renumbered themselves, or just re-ordered themselves. It’s also possible to number them by grabbing the drag pad on the left of the option & manually sorting them into order of importance. I know that when I first attempted the survey, (before discovering that I am not prepared for it,) it took me a bit to realize that it was reordering not renumbering.
Also wondering which Browser you use, it seems to work fine for me in Firefox 72.0.2 on Linux.
