Manager is not getting end dated in the backend for rehire

When a person is rehired previous manager details are not getting end dated in backend.

It shows two managers for the rehired person in the backend but in the frond end it looks fine.

SQL used:

select *

from fusion.per_manager_hrchy_dn

where person_id = 300004200303584

and trunc(sysdate) between effective_start_date and effective_end_date

order by manager_level, effective_end_date desc

We need to confirm whether this is a bug from oracle.
