Enabling Multiple submissions

I have found the guide on allowing multiple submissions, however the guide provided and images does not match the version of Canvas I have.  

I am currently in Edit assignment > Submission Type as per the guide however there is no option to select the number of submissions allowed as is indicated in the guide.

This is the guide I have found, am I looking in the wrong place?
