Can't remove shortcode

I’ve used this excellent plugin and another plugin has been added to the site which is casuing a problem, this plugin uses a shortcode in the RTE of [profile].
When I create my PDF the shortcode renders in the PDF and produces a load of unwanted stuff I can’t seem to remove it.
I tried making a minor adjustment to the code:

I replaced this:
add_filter( ‘the_content’, ‘wrapper_a2p_CreatePdf’, 9999 );

with this:
function remove_shortcode_from_pdf($content) {
$stripped_content = strip_shortcodes($content);
return $stripped_content;
}
$pdf_content = add_filter(‘the_content’, ‘remove_shortcode_from_pdf’);
add_filter( $pdf_content, ‘wrapper_a2p_CreatePdf’, 9999 );

I can’t get rid of this shortcode, any ideas would be greatly appreciate!!
