Clients Email not visible in confirmation email

Hi there,
I have used my calender for two years and all was fine.
The last two bookings I received don´t show name and email of client and I can not contact them.
When going to dashboard, it says “no booking available”.
But I receive a confirmation email with date and time and questions answered, name and email missing, so I can not work. The preview from my booking email shows everything correct including the formfields and it worked before.
WHAT CAN I DO?
HELP!!!
Please.
