I ran this script and yes there are two tables still locked.

SELECT SUBSTR(B.OWNER,1,8) "Owner",
B.OBJECT_TYPE,
SUBSTR(B.OBJECT_NAME,1,18) "Object_name" ,
DECODE(A.LOCKED_MODE,0,'None' ,1,'Null' ,
2,'Row-S',3,'Row-X' ,
4,'Share',5,'S/Row-X',
6,'Exclusive') "Locked_Mode",
A.SESSION_ID "Sess_ID",
SUBSTR(A.ORACLE_USERNAME,1,10) "User_name",
A.OS_USER_NAME "OS_User",
to_char(c.logon_time,'YYYY/MM/DD HH24:MI:SS') "Logon_Time"
FROM V$LOCKED_OBJECT A,DBA_OBJECTS B,v$session c
WHERE A.OBJECT_ID=B.OBJECT_ID
and a.session_id=c.sid
ORDER BY B.OWNER,B.OBJECT_TYPE,B.OBJECT_NAME;
