Not to worry. I see the issue.
This is to do with how that data type is stored. In general fields in the system which mentioned "No." in their title can handle alphanumeric content so ABC100 as an example. This means the sorting behaviour is not like an integer so, 1 2 3 4 5 6 7 8 9 10.
It is a good idea to look at the Cronus data to see how a job is setup there. If I am setting up a job task to demo I use the logic 100, 200, 300, 400, 500, 600 etc. This means I have some space for extra lines that I want to appear in the correct order so, if I later add 101 as a follow on task to 100 it flows correctly.
