Good evening everyone , After some help please

I have looked through the forums and tried several things already but no joy , so I think I am doing something silly but just need some guidance

I like to have my channels in a custom order e.g.

101 = BBC local area
102 = BBC2
103 = ITV Local area
...
106 = S*Y1
107 = S*Y1+1 etc etc

I have tried editing the custom_swap.txt file to read like the above , rebooted the machine but it does not make any difference.

I have tried the same with the custom_sort3.txt file but again no difference.

Could somebody advise

What file I need to update
Does anyone have an example I could edit

If I am barking up the wrong tree can anyone provide me with a "noddies" guide as to what I need to do

As always , Thanks for any help received
