I made a true/false ACF field called display_sorting. It appears that it returns null no matter if I set the default value or not.

<?php var_dump(get_field('display_sorting'));?>
returns :
[...].php:26:null

If I update the value from the page the field appears, the value will be correctly set to true or false.

<?php var_dump(get_field('display_sorting'));?>
will return this time :
[...].php:26:false
or
[...].php:26:true

My problem is that I would like to set the default value to true so I don’t have to set manually the value on x pages, but currently the default value isn’t properly read.

Am I missing something ?
