Performance document questionnaire with answers for worker and manager query

I am trying to build a query for Performance document questionnaire with answers for worker and manager query but its not giving correct answers.

When I add the tables for answers then row count increases.

Below is the query I am using.

Please suggest what join is missing.

SELECT DISTINCT papf.person_number Employee_ID
,ppnf.full_name Employee_Name

,paam.assignment_name
,ppos.date_start Start_Date
,papf1.person_number Manager_ID
,ppnf1.full_name Manager_Name,htpt.customary_name perf_doc_name

  --,he.evaluation_id       

  ,hes.section_type_code

  ,hsdv.name section_name

  ,he.status_code

  ,he.calibration_status
