I have created a form with several fields that must be filled before continuation is allowed. In configuration I chose that certain fields are always needed. It works well except that every now and then I receive a totally blank form where only the subject is filled in with an extra number (number of the subscription) but no email, no name, nothing else.Why is required detail not being shown and how can I arrange that it is? 
The content of some fields, though mandatory, are sometimes not being shown in my form responses
