[Solved] Radio buttons labels problem in form app

Hello,

I've got a problem with the labels on form app with radio buttons. My initial HTML code is fine but the template generates the labels in double, only for radio buttons. For the other inputs it's ok.

The template looks like this :

<fieldset>
<legend>Vous êtes</legend>
<p><span class="input-wrap"><perch:input type="radio" name="type" id="pro" value="professionnel" /> <perch:label class="after" for="pro">Un professionnel</perch:label></span> <span class="input-wrap"><perch:input type="radio" name="type" id="particulier" value="particulier" /> <perch:label class="after" for="particulier">Un particulier</perch:label></span> <span class="input-wrap"><perch:input type="radio" name="type" id="collectivite" value="collectivite" /> <perch:label class="after" for="collectivite">Une collectivité</perch:label></span></p>
</fieldset>

The generated HTML looks like this :

<fieldset>
<legend>Vous êtes</legend>
<p><span class="input-wrap"><input id="form1_pro1" name="type" type="radio" /><label for="form1_pro1"></label> <label class="after" for="form1_pro">Un professionnel</label></span> <span class="input-wrap"><input id="form1_particulier1" name="type" type="radio" /><label for="form1_particulier1"></label> <label class="after" for="form1_particulier">Un particulier</label></span> <span class="input-wrap"><input id="form1_collectivite1" name="type" type="radio" /><label for="form1_collectivite1"></label> <label class="after" for="form1_collectivite">Une collectivité</label></span></p>
</fieldset>

I've set the form before installing the Form App. So I deleted the region, installed the Form App et recreated the region. Could it be the source of the problem ? How to solve it ? I've updated many time te content via Back-Office to test and re-test but it didn't solve anything.
