FROM
   (SELECT id, Prospect_Id, CONCAT(Current_Status, '(', count(Current_Status), ')') AS MYVIEW     
    FROM prospectdata1
    GROUP BY Prospect_Id) A
GROUP BY  A.prospect_id
HAVING myview REGEXP 'PHONE_FOLLOW_UP.*DUPLICATE'

Output:

Expected Output:

Answer 1

You need to group by both Prospect_Id & Current_Status:

SELECT MIN(MinId) AS id
     , Prospect_Id
     , GROUP_CONCAT(CONCAT(Current_Status, '(', SUM(Cnt), ')') SEPARATOR ' , ') AS myview
FROM (
  SELECT Prospect_Id
       , Current_Status
       , COUNT(*) Cnt
       , MIN(id) MinId
   FROM prospectdata1
  WHERE Current_Status REGEXP 'PHONE_FOLLOW_UP.*DUPLICATE'
  GROUP BY Prospect_Id
      , Current_Status
) A
GROUP BY prospect_id
