Hello There!
My installations details are following:

Here is my problem. Some months ago I created a department called 'Remote Support'. After some weeks I deleted the department. However, it keeps showing up in some spots. I have noticed it in Tasks and the Dashboard:


I have already cleared the thread tables in my database. The department with such name also does not exist in the database.
select a.id,a.number,a.dept_id,b.name
from ost2_task as a join ost2_department as b on a.dept_id=b.id
+----+--------+---------+-----------------------------------------------+
| id | number | dept_id | name |
+----+--------+---------+-----------------------------------------------+
| 1 | 000155 | 9 | ADMIN |
| 2 | 000157 | 9 | ADMIN |
| 3 | 000158 | 9 | ADMIN |
+----+--------+---------+-----------------------------------------------+
3 rows in set (0.000 sec)
What can I possibly clear to get rid of the phantom department name?
