Personalisation Seetings Not gettng Saved

Hi Experts,

I created custom Component and View. When I click on personsalisation and increase/Decrease Pixels it is not making any impact.

Not sure why personalisation not working for me.

I reset thesettings ,still its not working.

Hint: when I remove Scrollbar  option ,Personalisation is working.

Code whcih i placed in my .HTM is

  <chtmlb:configCellerator actions               = "<%= controller->IF_BSP_WD_DYN_BTN_CONTROL~GET_LOCAL_TOOLBAR_BUTTONS( ) %>"
                         actionsMaxInRow       = "<%= controller->IF_BSP_WD_DYN_BTN_CONTROL~GET_NO_OF_VISIBLE_TOOLBAR_BTNS( ) %>"
                         downloadToExcel       = "TRUE"
                         editMode              = "ALL"
                         id                    = "ConfCellTable"
                         onRowSelection        = "select"
                         horizontalScrolling     = "TRUE"
                         reset                   = "FALSE"
                         personalizable        = "TRUE"
                        
                         showPersonalizeButton  = "TRUE"
<%--                         verticalScrolling      = "TRUE"--%>
                         selectedRowIndex      = "<%= ZITEMS->SELECTED_INDEX %>"
                         selectedRowIndexTable = "<%= ZITEMS->SELECTION_TAB %>"
                         selectionColumn       = "<%= lv_cellerator_selectioncolumn %>"
                         selectionMode         = "MULTI"
                         table                 = "//ZITEMS/Table"
                         usage                 = "ASSIGNMENTBLOCK"
                         visibleFirstRow       = "<%= ZITEMS->VISIBLE_FIRST_ROW_INDEX %>"
                         visibleRowCount       = "20"
