Where can I see the the fields in subtask when Im inside the subtask?

This is a problem when Im in “my task” view as I can not see all fields of subtasks.
I know I can see the fields in the general project view when I expand the subtree of the task and show the subtask. But I don’t understand why I can not see those fields in in the subtask itself or in the my task list view. I need to tag sometimes the subtasks ,for example with “WIP” and I don’t see how unless I go to the general project.

Could you share an anonymized screenshot please?
