Can't create group in front end. error message "Please complete the previous step 2 first."

Hi,

When I want to create a new group on the front end I receive the below error message.

"Please complete the previous step 2 first." I think it might be something with either the created form or maybe user rights?

Do you maybe know how to fix this?

p.s. I'm able to create a group in the back end.

Thanks in advance.
