hibernate adding Id column field while building query - spring

Question

Hibernate not creating correct query, In API request I have passed sort=employee.firstName that should return records sort by firstName but hibernate some how adding extra field case_id after firstName. I have debug the code and in sort only one field is there which is employee.firstName, so my question is how hibernate is adding case_id to the query.
Below is my API URL.
/api/v1/cases?sort=employee.firstName,ASC&size=50&page=0&statusCategories=open,in_progress&filter=caseType:customer_care
I have not passes sort by case_id instead sort by firstName is passed.
Hibernate Query below:
SELECT
case0_.case_id AS case_id1_8_,
case0_.archived_from AS archived_from2_8_,
case0_.assignee_id AS assignee_id3_8_,
case0_.status_id AS status_id15_8_,
case0_.type AS type4_8_,
case0_.category_id AS category_id5_8_,
case0_.employeegroup_id AS employeegroup_id11_8_,
case0_.created_by AS created_by6_8_,
case0_.created_date AS created_date7_8_,
case0_.customer_id AS customer_id8_8_,
case0_.description AS description9_8_,
case0_.due_date AS due_date10_8_,
case0_.eventmanager_id AS eventmanager_id12_8_,
case0_.resolution_date AS resolution_date13_8_,
case0_.resort_id AS resort_id14_8_,
case0_.topic AS topic16_8_
FROM
CASE case0_
LEFT OUTER JOIN employee client1_ ON
case0_.created_by = client1_.employee_id
WHERE
(case0_.status_id IN (
SELECT
casestatus2_.case_status_id
FROM
case_status casestatus2_
WHERE
casestatus2_.category IN (? , ?)))
AND (case0_.archived_from IS NULL)
AND case0_.type =?
ORDER BY
client1_.firstname ASC,
case0_.case_id ASC offset ? ROWS FETCH NEXT ? ROWS ONLY
[Screenshot in debug mode, as u can see the sort variable only having one field][1]

Repositery Code:
#Repository
public interface CaseRepository extends MaxxtonJpaRepository<Case, Long> {
#Query(nativeQuery = true, value = "SELECT assignee_id FROM case WHERE assignee_id IN (SELECT employee_id FROM employee WHERE group_Id= :employeeGroupId ) group by assignee_id")
public List<Long> fetchEmployees(#Param(value = "employeeGroupId") Long employeeGroupId);
}
Another Repositery class:
#NoRepositoryBean
public interface MaxxtonJpaRepository<ENTITY, ID extends Serializable> extends FieldFilterRepository<ENTITY, ID>, JpaSpecificationExecutor<ENTITY> {
<P> List<P> findAll(Specification<ENTITY> spec, Class<P> projection);
<P> Page<P> findAll(Specification<ENTITY> specification, Class<P> projection, Pageable pageable);
ENTITY saveAndRefresh(ENTITY entity);
Iterable<ENTITY> saveAllAndRefresh(Iterable<ENTITY> entities);
}
How this case_id gets added in order by.
