Dear Carloalberto,
I don't have your login details anymore. Please provide them below.
Also, we're going to release a complete update of Toolset this or next week, and this should be fixed as there were some big changes done. I'm currently testing the validation process updated by our developers.
But please provide your login, I'll check what is wrong. Also, please write where to look for the form.
Regards,
Paweł
