WPFORMS not transmitting name to mailchimp

I use the pro version of wpform plugin and want to add a mailchimp newsletter contact by adding the mailchimp button to my contact formular. That seems to work so far, bot only the email adress is saved in a new contact in the mailchimp list.
First name and last name are not saved (and stay empty) even thou the fields are filled out in the contact form.
Can I get some help from your side to fix that problem?
