List box values in mosule pool

Question

hi
i am currently working with screen exit where i am populating values to a list box using customl table.
the problem is that when i am creating new entries in custom table the old entries are also getting displayed in list box even though i have deleted previous entries.
here is the code
PROCESS ON VALUE-REQUEST.
Create drop down box for listbox1
  FIELD proj-zz_list1 module create_listbox1.
MODULE create_listbox1 INPUT.
                  TYPE DECLERATION.
  TYPES:
         BEGIN OF ty_list1,
        Data type for listbox field
           list1 TYPE zgfbm_listbox1,
         END OF ty_list1.
                  VARIABLES DECLARATION                              *
  DATA:
      Internal table used to store userfield.
        li_list1 TYPE STANDARD TABLE OF ty_list1.
                  PROCESSING LOGIC                                   *
clear: proj-zz_list1, li_list1.
      Select listbox1 from value table into internal table
  SELECT     zz_list1
    FROM     zgfbm_list1
  INTO TABLE li_list1.
Create listbox corresponding to field in proj table
  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield        = 'PROJ-ZZ_LIST1'
      value_org       = 'S'
    TABLES
      value_tab       = li_list1
    EXCEPTIONS
      parameter_error = 1
      no_values_found = 2
      OTHERS          = 3.
  IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
