GuiTextListCtrl drops last TAB item

I am seeing a bug in multiple places in my game for the GuiTextListCtrl. If it is updates only once, it will drop off the far right value. If it is updated more than once it appears. So in cases like my playerlist gui it is barely noticeable. But in the end game gui you can see it clearly.

Here is my gui script:

new GuiTextListCtrl(EndGameGuiList) {
            canSaveDynamicFields = "0";
            Profile = "GuiTextArrayProfile";
            HorizSizing = "relative";
            VertSizing = "relative";
            position = "2 2";
            Extent = "304 8";
            MinExtent = "8 8";
            canSave = "1";
            Visible = "1";
            hovertime = "1000";
            enumerate = "0";
            resizeCell = "1";
            columns = "0 162 213 268";
            fitParentWidth = "1";
            clipColumnText = "0";
         };

Here is my script to load the values:

function EndGameGui::updateDMGameEndScore(%this, %clientId, %name, %kills, %deaths, %score )
{
   %text = StripMLControlChars(%name) TAB %kills TAB %deaths TAB %score;

   // Update or add the player to the control
   if (EndGameGuiList.getRowNumById(%clientId) == -1)
      EndGameGuiList.addRow(%clientId, %text, %clientId);
   else
      EndGameGuiList.setRowById(%clientId, %text);

   // Sorts by score
   EndGameGuiList.sortNumerical(1,false);
   EndGameGuiList.clearSelection();
}

I am positive it is not my data because if I change this line:

%text = StripMLControlChars(%name) TAB %kills TAB %deaths TAB %score;

to

%text = StripMLControlChars(%name) TAB %kills TAB %score TAB %deaths ;

I get the same problem but the %score value is present, just where %deaths used to be, and the %deaths is not.

Any ideas?
