hidden-fields-container

Hi, after updating to latest versions of Contact 7 and WP I got this hidden field on my contact 7 form (before all the other fields), which is not hidden actually but looks like an empty field with borders (screenshot https://snipboard.io/8C0ZfT.jpg).

What is that? It was never there before.

I tried to hide it by css but it's not working:

#hidden-fields-container fieldset {

    display: none !important;

}

The code of the form apparently has no hidden fields:

<div class="row">

<div class="col-md-6">

<p style="margin: 0; color: rgba(0 0 0 / 0.3); font-size: 12px;">Nome</p>

[text* text-619 placeholder "Il tuo nome"]

</div>

<div class="col-md-6">

<p style="margin: 0; color: rgba(0 0 0 / 0.3); font-size: 12px;">Email</p>

[email* email-899 placeholder "La tua email"]

</div>

<div class="col-md-6">

<p style="margin: 0; color: rgba(0 0 0 / 0.3); font-size: 12px;">Telefono</p>

[tel tel-957 placeholder "Il tuo telefono"]

</div>

<div class="col-md-6">

<p style="margin: 0; color: rgba(0 0 0 / 0.3); font-size: 12px;">Oggetto</p>

[text* text-353 placeholder "Il tuo progetto"]

</div>

<div class="col-md-12">

<p style="margin: 0; color: rgba(0 0 0 / 0.3); font-size: 12px;">Messaggio</p>

[textarea* textarea-889 10x4 placeholder "Dimmi di più"]

</div>

<div class="col-md-12">

[acceptance acceptance-666 optional] Ho letto ed accetto la <a style="color:#DB588F;" href="https://adpwebdesign.it/privacy-policy/" target="_blank"> privacy policy </a> del sito web. [/acceptance]

</div>

<div class="col-md-12">

[submit "Invia"]

</div>

</div>

thanks for your help
