Task categories are displayed in a project based on their sort order in the configuration screen. This order may be changed by clicking on Edit in the upper right corner of the screen.
An up and down arrow will appear to the left of each task category and may be used to change its position within the list. For example, if you want the Translation task category to be in position 4, you would need to keep clicking on the down arrow until it is in the fourth spot on the list.
In this example it has been moved to position 2 within the task categories list:
Once the task categories have been sorted appropriately, click on OK in the upper right of the screen to save your changes:
If you open a new project, scroll down when viewing the New project details Tab. For existing projects, it is simply titled "Project Details".
Within this tab, you will see a Requirements section and then a Tasks option. Task categories appear in this section and as shown in the image below, the Translation Task Category is now second in the list.
