why can’t the relation manager from the address appear when creating an order

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?
