You certainly make mistakes use ACF, the short code works perfectly with ACF.
To display ACF content please read this from the ACF author :
https://www.advancedcustomfields.com/resources/get_field/
See the following to know how use shortcodes in your theme display (with ACF value reach using get_field() ):

https://wordpress.stackexchange.com/questions/173844/apply-filtersthe-content-content-vs-do-shortcodecontent
As an example, you can use that snippet ( acf_wuspsc_field is the name of your field from ACF settings) :
<?php
// get the ACF field content
$scvalue = get_field( "acf_wuspsc_field", false, false );
// if ACF is not empty
if( $scvalue ) {
// display the shortcode content
echo apply_filters('the_content', $scvalue);
}
?>
I hope this help,
