Prohibits on Checkbox not working

I have form with a checkbox and a date picker. Neither are required but both should never be fillable/submittable together. I am using the prohibits rule so one blocks the other.

Forms\Components\Checkbox::make('start_immediately')
    ->prohibits('start_date'),

Forms\Components\DatePicker::make('start_date')
    ->prefixIcon('heroicon-o-calendar')
    ->minDate(now())
    ->native(false)
    ->prohibits('start_immediately'),


Leaving the fields blank works, only ticking start_immeditately works, however selecting a start_date but leaving start_immediately blank throws a validation error as shown in the image as the start_immeditately field is present even if it’s value is 
false
. Is there are way around this?

Solution
I can use a custom rule like so which fixes this. I think it’s the only way to make it work as the built-in rules don’t always play well with checkboxes

Forms\Components\Checkbox::make('start_immediately')
    ->rules([
        function(Get $get) {
            return function (string $attribute, $value, Closure $fail) use ($get) {
                if ($value &&  $get('start_date')) {
                    $fail('Please select either start immediately, a start date or leave both blank.');
                }
            };
        }
    ]),
Forms\Components\DatePicker::make('start_date')
    ->prefixIcon('heroicon-o-calendar')
    ->minDate(now())
    ->native(false),
