exclude_if rule does not work

Hello, Using laravel 12 and the package: Laravel Excel.

https://docs.laravel-excel.com/3.1/imports/validation.html

I have an excel file with these column names:

Batch, Time, Profile, Beans, In (g), Out (g)

I need to validate rows only if the value in the Batch column is not: SUM

The problem I have is that the validations happen even if the value in the column is SUM. I get the errors on the row where the value in the column Batch is SUM.

I tried 3 different ways:

My import class:

<?php

namespace App\Imports;

use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToCollection;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
use Maatwebsite\Excel\Concerns\WithValidation;
use App\Models\Coffee;
use App\Models\GreenBean;

use Illuminate\Support\Facades\Log;

class RoastImport implements ToCollection, WithHeadingRow, WithValidation
{
    private $bean;

    /**
     * @param Collection $rows
     */
    public function collection(Collection $rows)
    {
        foreach ($rows as $row) {
            $name = $row['profile'];
            $weight = $row['out_g'];
        }
    }

    public function rules(): array
    {
        return [
            'beans' => ['exclude_if:batch,SUM', 'required', 'exists:green_beans,name'],
            'out_g' => ['exclude_if:batch,SUM', 'required', 'numeric'],
        ];

//I also tried:
 return [
	'out_g' => Rule::when([fn($input) => $input->batch != 'SUM', ['required', 'numeric']),
	'beans' => Rule::when(fn($input) => $input->batch != 'SUM', ['required', 'exists:green_beans,name']),
]

//and
return [
            'out_g' => Rule::when(fn($input) => $input['batch'] != 'SUM', ['required', 'numeric']),
            'beans' => Rule::when(fn($input) => $input['batch'] != 'SUM', ['required', 'exists:green_beans,name']),
        ];
    }

}

Please help.
