Viewfield views rendering makes Views Nivo Slider stop working

Hello drupal,

I made a page with a Viewfield inside. Now, when I activate the output from the meta-tag module (for example the page-discription) nivo-slider stops sliding. The same Nivo Slider View works well as a block on the same page.
When I look at the html output I see the following differents:

Slider is working well:

jQuery.extend(Drupal.settings, { "basePath": "/", "admin_menu": { "margin_top": 1, "position_fixed": 1, "tweak_tabs": 1 }, "colorbox": { "transition": "elastic", "speed": 350, "opacity": "0.85", "slideshow": false, "slideshowAuto": false, "slideshowSpeed": 2500, "slideshowStart": "", "slideshowStop": "", "current": "{current} of {total}", "previous": "« Prev", "next": "Next »", "close": "Close", "overlayClose": true, "maxWidth": "100%", "maxHeight": "100%" }, "views_nivo_slider": { "views-nivo-slider-slider_gaestebuch-default": { "startSlide": 0, "effect": "fade", "slices": 1, "animSpeed": 1000, "pauseTime": 8000, "directionNav": true, "directionNavHide": true, "controlNav": false, "controlNavThumbs": false, "controlNavThumbsFromRel": false, "keyboardNav": false, "pauseOnHover": true, "manualAdvance": false, "captionOpacity": 0.8 }, "views-nivo-slider-slider_gaestebuch-block_1": { "startSlide": 0, "effect": "fade", "slices": 1, "animSpeed": 1000, "pauseTime": 8000, "directionNav": true, "directionNavHide": true, "controlNav": false, "controlNavThumbs": false, "controlNavThumbsFromRel": false, "keyboardNav": false, "pauseOnHover": true, "manualAdvance": false, "captionOpacity": 0.8 } } });

Slider stops sliding:

jQuery.extend(Drupal.settings, { "basePath": "/", "admin_menu": { "margin_top": 1, "position_fixed": 1, "tweak_tabs": 1 }, "colorbox": { "transition": "elastic", "speed": 350, "opacity": "0.85", "slideshow": false, "slideshowAuto": false, "slideshowSpeed": 2500, "slideshowStart": "", "slideshowStop": "", "current": "{current} of {total}", "previous": "« Prev", "next": "Next »", "close": "Close", "overlayClose": true, "maxWidth": "100%", "maxHeight": "100%" }, "views_nivo_slider": { "views-nivo-slider-slider_gaestebuch-default": { "startSlide": [ 0, 0 ], "effect": [ "fade", "fade" ], "slices": [ 1, 1 ], "animSpeed": [ 1000, 1000 ], "pauseTime": [ 8000, 8000 ], "directionNav": [ true, true ], "directionNavHide": [ true, true ], "controlNav": [ false, false ], "controlNavThumbs": [ false, false ], "controlNavThumbsFromRel": [ false, false ], "keyboardNav": [ false, false ], "pauseOnHover": [ true, true ], "manualAdvance": [ false, false ], "captionOpacity": [ 0.8, 0.8 ] }, "views-nivo-slider-slider_gaestebuch-block_1": { "startSlide": 0, "effect": "fade", "slices": 1, "animSpeed": 1000, "pauseTime": 8000, "directionNav": true, "directionNavHide": true, "controlNav": false, "controlNavThumbs": false, "controlNavThumbsFromRel": false, "keyboardNav": false, "pauseOnHover": true, "manualAdvance": false, "captionOpacity": 0.8 } } });

It seems that all slider parameters are double.
Could this be a problem with the viewfield-module?

Thanks in advance and sorry for my bad english ;-)
