We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi Jacopo,
Are you facing this issue with every model, or is it specific to this one? Is there any reason to choose frictionless contact? Will you please change it to the frictional to see if this problem is related to the choice of the selection of the contact? 

Regards,
Sampat
