I am using the events booking module successfully but there is a slight issue.
When people register as a group registration and I selected to export the members individually in the configuration the individual members names appear in the Firstname field only, ie first Name : Richard Lane Last Name : (nothing)
I don't really understand the issue (seems you forgot to attach the screenshot). Maybe you can submit a support ticket, we will help checking the settings on your site to see why it happens and get it sorted?
