[Accessibility] Orphaned form label

Hi,

Im currently having an accessibilty issue. My service provider just send me some notifications about “Orphaned form label” issue on one of my form.
The reason is a got 2 radios buttons groups my Im not able to hade a “for” attribute to the label.

Just so you know, here is my code, so you can see there is no “for” attribute on the very first label :

<div class="ff-el-group custom-options">
    <div class="ff-el-input--label ff-el-is-required asterisk-right">
        <label aria-label="Cet article vous a-t-il été utile ?">Cet article vous a-t-il été utile ?</label>
    </div>
    <div class="ff-el-input--content">
        <div class="ff-el-form-check ff-el-form-check-">
            <label class="ff-el-form-check-label" for="input_radio_dc2e77c1e9de5e92630d6b0d4c96d322">
                <input type="radio" name="input_radio" data-name="input_radio" class="ff-el-form-check-input ff-el-form-check-radio" value="Oui" id="input_radio_dc2e77c1e9de5e92630d6b0d4c96d322" aria-label="Oui" aria-invalid="false" aria-required="true">
                <span>Oui</span>
            </label>
        </div>
        <div class="ff-el-form-check ff-el-form-check-">
            <label class="ff-el-form-check-label" for="input_radio_74b91a177b4d405e5c3dd6d3fee297c8">
                <input type="radio" name="input_radio" data-name="input_radio" class="ff-el-form-check-input ff-el-form-check-radio" value="Non" id="input_radio_74b91a177b4d405e5c3dd6d3fee297c8" aria-label="Non" aria-invalid="false" aria-required="true">
                <span>Non</span>
            </label>
        </div>
    </div>
</div>

Do you have a solution for this ?
Cheers,
