during page load, the $options is an array with zero elements. so I modified my code and now it works.

add_filter('acf/location/rule_match/post_category', 'acf_location_rules_match_post_category', 10, 3);
function acf_location_rules_match_post_category( $match, $rule, $options )
{
    $current_cat = $options['post_category']; // array, user selection
    $rule_cat_id = (int) $rule['value']; // numeric, rule

 	global $pagenow;
 	if (count($current_cat)==0 && $pagenow=='post.php'){
		// if we're editing post and not adding a new post
 		$current_cat= wp_get_post_categories($options["post_id"]);	
 	}
 	
    if($rule['operator'] == "<=")
    {
    	$match = false;
    	
		$match = in_array($rule_cat_id, $current_cat); //check if main cat
	
		if (!$match){
			// check the subcategories instead so first get the subcats
			$args=array(
				'child_of'=>$rule_cat_id,
				'hide_empty'=>0
			);
			$subcats = get_categories($args);
			foreach ($subcats as $subcat){
				if (in_array($subcat->term_id, $current_cat))
				{
					$match = true;
					break;	
				}
			}
		} 
    }
    return $match;
}
