This code fixes the WordPress save function. I have also submitted this as a bug so hopefully they fix it.

add_action( 'admin_print_footer_scripts', 'mediaArrayFix', 11 );
	function mediaArrayFix() {
		// Make sure the media-views script has been enqueued.
		if(!did_action( 'wp_enqueue_media' ) ){ return; }
		?>
		<script>
		wp.media.view.AttachmentCompat.prototype.save = function( event ) {
			var data = {};
			if ( event ) { event.preventDefault(); }
			_.each( this.$el.serializeArray(), function( pair ) {
				if ( /\[\]$/.test( pair.name ) ) {
					if ( undefined === data[ pair.name ] ) { data[ pair.name ] = []; }
					data[ pair.name ].push( pair.value );
				}else{ data[ pair.name ] = pair.value; }
			});
			this.controller.trigger( 'attachment:compat:waiting', ['waiting'] );
			this.model.saveCompat( data ).always( _.bind( this.postSave, this ) );
		};
		</script>
		<?php
	}
