why can't the relation manager from the address appear when creating an order but when editing and viewing it appears

 public static function getRelations(): array
    {
        return [
            AddressRelationManager::class,
        ];
    }

I have already had relations in model orders

 public function address()
    {
        return $this->hasOne(Address::class);
    }

Why is it still not showing up when placing an order?
