Some icons not show in toolbar

[Alexscandal]

For ex not show "image" icon.
Code:

<?=$form->field($model, 'name')->widget(TinyMce::class, [
      'options' => ['rows' => 10],
      'language' => 'ru',
      'clientOptions' => [
            'plugins' => [
                "advlist autolink lists link charmap print preview anchor",
                "searchreplace visualblocks code fullscreen",
                "insertdatetime media table contextmenu paste image"
            ],
            'toolbar' => "undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image code",
       ]
])?>

"image" exists in "plugins" and "toolbar" sections.
