SQL Case command in joined script returns too many rows

Trying to eliminate the duplicates / what the heck am I doing ???

select PONUMBER, ord, POLNESTA from POP10110 where PONUMBER = '54_0015328'

select
RTRIM(pol.PONUMBER) AS 'PO'
,pol.ord
,CASE
WHEN pol.POLNESTA = 1 THEN 'New'
WHEN pol.POLNESTA = 2 THEN 'Released'
WHEN pol.POLNESTA = 3 THEN 'Change Order'
WHEN pol.POLNESTA = 4 THEN 'Received'
WHEN pol.POLNESTA = 5 THEN 'Closed'
WHEN pol.POLNESTA = 6 THEN 'Cancelled'
END AS 'Status'
from POP10110 pol

INNER JOIN POP10100 poh on pol.PONUMBER = poh.PONUMBER
LEFT JOIN XW_ReqLine rll on poh.PONUMBER = rll.PONbr
where pol.PONUMBER = '54_0015328'
