Laravel Eloquent未获取全部数据库记录问题求助

执行NumberConfiguration::all()时，仅返回1条记录：

[{"id":1,"created_at":"2022-09-13 09:48:51+0200","updated_at":"2022-09-13 09:49:12+0200","block_start":"41582550003","block_end":"41582550003","number_block_id":1,"special_numbers":null}]

但PostgreSQL数据库中实际存在2条记录（见附图）。已尝试注释父类中的Observer，问题仍未解决。

以下是NumberConfiguration模型代码：

class NumberConfiguration extends BaseConcreteProductConfiguration
{

protected $table = 'shop.numbers_configurations';

// Needs to be present in every ConcreteConfiguration file who has a Observer with action on cart to order
protected $fillable = [ 'updated_at' ];


protected $casts = [ 'special_numbers' => 'array' ];

public static function getValidations(string $prefix = ''): array
{
    return [
        $prefix . 'block_start'     => [ 'nullable' ],
        $prefix . 'block_end'       => [ 'nullable' ],
        $prefix . 'number_block_id' => [ 'nullable', 'numeric' ],
        $prefix . 'special_numbers' => [ 'nullable' ],
    ];
}

public static function getManager(): ConfigurationManagerInterface
{
    return new NumberConfigurationManager();
}

public function getDescription(): ?string
{
    $numberBlock = NumberBlock::find($this->number_block_id);

    if (!is_null($numberBlock)) {
        $numbers = $numberBlock->numbers()->pluck('did');

        if (!empty($numbers)) {
            return NumberManager::groupNumberToDisplayWithLocalPrefix(NumberManager::groupNumbersByRange($numbers))
                ->reduce(fn($a, $b) => $a . $b . ' ');
        } else {
            \Log::warning('configuration description not available, no numbers for block: '
                          . $this->number_block_id);
        }
    }

    return null;
}
}

恳请各位提供帮助。
