I am a workspace owner, why my tasks are not showing up in the list.

There are two reasons why you may not see your tasks in the list:

1. If another member created and assigned a task to you, and then changed the assignee or the project you have no access to.
2. If the project your task belongs to has been archived or deleted.

Note: Your user role within the workspace doesn't affect task visibility in the list. Also, pay attention to the filters you use, since the requested data might not match the selected criteria.
