I’ve encountered an issue where sub-tasks suddenly stopped appearing under their parent task.
As shown in the attached image, there are multiple sub-tasks under the parent task, but they are no longer visible.
Could you please advise on how to resolve this?
Thank you for your assistance.

When converting a regular task to a sub-task, the parent task selection field, which was previously available, no longer appears, as shown in the attached image.
