Usunąć import nadrzędnego tablicy arkusz do kolekcji lub tablicy w pakiecie Laravel Excel

Chcę zaimportować do programu Excel, ale tylko w indeksie arkusza[0], ale kiedy używam metoda to) collection lub toArray, wiersze, owinięte w tablicy indeksów arkusza:

Chcę usunąć owinięty nadrzędny tablicy, jak to zrobić?

Oto mój kod:

Import.php

<?php

namespace App\Imports;

use Maatwebsite\Excel\Concerns\Importable;
use Maatwebsite\Excel\Concerns\SkipsEmptyRows;
use Maatwebsite\Excel\Concerns\WithCalculatedFormulas;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;

class Import implements SkipsEmptyRows,
                        WithCalculatedFormulas,
                        WithMultipleSheets
{
    use Importable;

    /**
     * Select sheet by index and how they are
     * mapped to specific import object.
     *
     * @return array
     */
    public function sheets(): array
    {
        return [
            0 => new static(),
        ];
    }
}

Kontroler:

$filePath = 'import-excel.xlsx';
$import = new Import();
$rows = $import->toCollection($filePath);

dd($rows->toArray());

oczekiwany wynik:

[0] => Array(
    [0] => *Contact Name
    [1] => *Contact Email
    [2] => *Contact Address
)

[1] => Array (
    [0] => Talia Oktaviani S.Psi
    [1] => [email protected]
    [2] => Ds. Abdul No. 618 Tarakan 11408 KalU
)

Rzeczywisty Wynik:

Array(  <== ***I want remove this.***
    [0] => Array(  <== ***I want remove this.***
        [0] => Array(
            [0] => *Contact Name
            [1] => *Contact Email
            [2] => *Contact Address
        )

        [1] => Array (
            [0] => Talia Oktaviani S.Psi
            [1] => [email protected]
            [2] => Ds. Abdul No. 618 Tarakan 11408 KalU
        )
    )  <== ***I want remove this.***
