The Caption on the Flexslider Views Slideshow is using a 'P' element as wrapper around the caption field. It should work like
but it works like:
So the Field caption tekst is placed outside the caption tags. This also fails using the P element directly within views. So it looks as if it goes wrong there. But to solve this we can use a SPAN around the caption field. this can be done via changing line 57 in flexslider_views_slideshow.module to
$view->field[$fieldname]->options['element_type'] = 'span';
This solution works perfectly.
