engagement studio help

Hi

i am new to engagement studio and need some help in setting up a nurturing journey. I have attached a screenshot of my set up - i need advice on some aspects. The idea is prospects get sent an email and complete a form and get added to a list. if they don't complete a form they get sent another email and its the same process (this is done 4 times) however i have done two test runs and it seems like anytime one of us fills in the form it doesn't get added to "yes" on the form completion action. this is the main issue at the moment - i think it might have something to do with ip address (we have completed the form multiple times prior) 

the other thing i want to know is how to ensure if someone receives an email they get added to the "yes" list and then not receive the rest of the emails - as it stands no matter what route we choose  we all get every email.
