There is a problem when I’m doing an export of custom post with Toolset Type checkbox field :

Backend fatal error: PHP Fatal error: Uncaught TypeError: array_filter(): Argument #1 ($array) must be of type array, bool given in /xxxxx.fr/wp-content/plugins/admin-columns-pro/addons/types/classes/Export/Field/Checkboxes.php:17

In wp-content/plugins/admin-columns-pro/addons/types/classes/Export/Field/Checkboxes.php

I replace :
array_filter( $field->get_values_as_labels( $id ) )

by :
array_filter( (array)$field->get_values_as_labels( $id ) )

Best regards,
Guillaume
