				if( 'empty_line' == $element['type'] )
				{
					if( ! ( isset( $element['element_display'] ) && 'frontend' == $element['element_display'] ) )
					{
						$new_post[ $key ] = 'xxx';
					}
				}

				if( 'headline' == $element['type'] )
				{
					if( ! ( isset( $element['element_display'] ) && 'frontend' == $element['element_display'] ) )
					{
						$new_post[ $key ] = $element['label'];
					}
				}

				if( ! empty( $new_post[ $key ] ) )
				{
					if( $element['type'] != 'hidden' && $element['type'] != 'decoy' )

should be:

				if(isset( $element['type'] ) && 'empty_line' == $element['type'] )
				{
					if( ! ( isset( $element['element_display'] ) && 'frontend' == $element['element_display'] ) )
					{
						$new_post[ $key ] = 'xxx';
					}
				}

				if(isset( $element['type'] ) && 'headline' == $element['type'] )
				{
					if( ! ( isset( $element['element_display'] ) && 'frontend' == $element['element_display'] ) )
					{
						$new_post[ $key ] = $element['label'];
					}
				}

				if( ! empty( $new_post[ $key ] ) )
				{
					if(isset( $element['type'] ) && $element['type'] != 'hidden' && $element['type'] != 'decoy' )

seams that when submitting with Captcha v2 the $element is no array, its a string… And that makes an error and the form is not submitted.
Please check beforehand, if its set then there is no error and the form is correctly submitted.
