Assistance please

I created a separate mailing list for 4 of my subscribers but when I tried to add subscribers to this list (already in my main mailing list), I get this error message:
Error: Incorrect table name
‘wp_newsman_lst_radical_intimacy_love_messages_from_your_body_call_1

Can you provide assistance as to what I need to do to correct this?

Thank you!!
