I have tried to set up badges on a solution of ours, and couldn't get it to work using the guide.
I then thought that it might have been our solution, and tried to set it up on a 1.13 demo we have.
But neither here does it work. It shows the badges but there is no styling on them see image below, you see all the badges in the code but non on the product except % discount.
This is our demo solution - http://smartpage.swift.dwdemo.dynamicweb-cms.com/e-bikes/e-mountain-bikes
