I've created a subtask screen that is configured to customize the 'Create New screen'. The new screen includes two field tabs as well as all of the custom fields. However, when I click on the Create Subtask Screen, it displays all of the fields in the same screen, but the field tab is missing. For the most part, all of the fields are displayed on a single long screen. Despite the fact that the Create New screen has two tabs, I am unable to see them. Please assist with this matter.
