Basicprimitives org chart node preview working wrong

Question

I successfully create a organizational chart with BasicPrimitives-orgChart but I have a problem with the node's preview when you do mouse hover. Sometimes randomly gray "preview" node appears on the left of the screen.

Sometimes the preview shows correctly

But somethimes appear the gray node

My fucntion to chart create

function buildChart() {
    var options = new primitives.orgdiagram.Config();
    var jsonString = $("[id$=txhDat]").val();
    var datos = JSON.parse(jsonString);
    var arrayItem = [];
    for (index = 0; index < datos.length; index++) {
        var objUbica = datos[index];
        var item = new itemUbica(objUbica.cve, objUbica.name, objUbica.parent, objUbica.index);
        var itemFinal = new primitives.orgdiagram.ItemConfig(item);
        arrayItem[arrayItem.length] = itemFinal;
    }
    options.items = arrayItem;
    options.cursorItem = 0;
    options.templates = [getTemplateUbica()];
    options.onItemRender = onTemplateRender;
    options.hasButtons = primitives.common.Enabled.True;
    options.hasSelectorCheckbox = primitives.common.Enabled.False;
    options.onButtonClick = function (e, data) {

        switch (data.name) {
            case "move":
                $("[id$=]")
                dialogMoveOp(data.context.cveUbica, data.context.ubica);
                break;
        }
    };
    jQuery("#divChart").orgDiagram(options);
}

Also this happend just after the first render I dont manipulate anything in the DOM.
