Clciking listview header with icon loses right justify

[Blobby]

Hello peeps,

I have a listview with an ascending/descending icon available on each header which shows the sort order of the column.
My problem is that my numeric field (file size) is right justified when i launch the program and populate the listview but when i click on this header it adds the icon showing the currnt sort order but the column reverts to left justify. Heres my code...what do i do to make it right justify again? Thanks

Private Const HDI_IMAGE = &H20
Private Const HDI_FORMAT = &H4
Private Const HDI_TEXT = &H2
 
Private Const HDF_BITMAP_ON_RIGHT = &H1000
Private Const HDF_BITMAP = &H2000
Private Const HDF_IMAGE = &H800
Private Const HDF_STRING = &H4000

   With HD
      .mask = HDI_IMAGE Or HDI_FORMAT
      .pszText = LView.ColumnHeaders(colNo + 1).Text

         If colNo = 1 And LView.Name = "MatchFiles" Then
