For information , you are in the french forum.
For the job sorting list , you probably miss the line which explain that each row of selectable depend of your role .
First if you have a tank role , second if healer , third if Dps and 4th if "others" , so you must change second for you .
And under the 4 rows , you have another one to choice order for each role ( pld drk gnb then war or drk war gnb then pld for example .
