Select2 is not loading the selected values when edit the row the first time in a page

Hi,

I have tried to create a test case but there is any issue adding the libs. If you can give me any clue about how to finish the test case I will: https://live.datatables.net/kaquqexa/3/

I have one field of type select2 (blend) with option: multiple and other (format) allowing only single values. When I load the first time the page and edit a row the modal editor is loaded without the selected values. However, if I edit a second time the values are loaded.

var editor = new DataTable.Editor({
        ajax: {
            create: '/save/${id}',
            edit: '/update/',
            remove: '/delete/',
            idSrc: 'id'
        },
        fields: [
            {
                name: 'DT_RowId',
                type: 'hidden',
            },
            {
                label: 'Blend',
                name: 'blend',
                type: "select2",
                separator: ":",
               opts: {
                    "multiple": true,
                    "allowClear": true,
                    "separator": ":",
                       "placeholder": {
                           "id": "",
                           "text":"(Select blends)"
                       }
                },
                options: [
                    { label: '', value: '' },
                    { label: '9000 Extra', value: '9000'},                    
                    { label: '9001 RA', value: '9001'},                    
                    { label: '9001 Col', value: '9001'},                    
                    { label: '900R Classic', value: '900R'}
                    
                ]
            },
            {
                label: 'Format',
                name: 'format',
                type: 'select2',
                options: [

            },
            {

                type: 'select',
                options: [
