Multiple content entries being created

Hello

Not quite sure how to describe this issue so please bear with me

Since the upgrade to 7.x-3.18 everytime a webform is submited on my site it creates a new entry instead of appending it to the webform for further analysis (see image webform.jpeg) each entry is a person who has visited the site and completed a "contact us" webform

as such there are no details visible in analysis or submissions, it is simply blank

My current setup is as follows

1. Created a "Contact Us" content type
2. Home » Administration » Configuration » Content authoring
I have associated the "Contact Us" content type as a Webform-enabled content types
3. Created the menu link for people to enter their details

Can you advise what might be wrong here?
