Task number length different in Projects Form Vs Self Service Projects Page

Why there is different length for the task number field in the tasks created from self service application and tasks from project form. This is inconsistent and causing lot of unwanted issues. How do we make it consistent so we have same task number length in both the places.

For example, task number field is accepting 100 characters in the self service application for project creation whereas in project form, it accepts only 25 characters.

To give you further details, pa_proj_elements.ELEMENT_NUMBER is having a length of VARCHAR2(100) which is being populated for task number from project self service (HTML) page whereas pa_tasks.TASK_NUMBER is having a length of VARCHAR2(25) which is being populated for task number from Project Form.
