Product Customisation issue

[websitebuilder]

Hi guys,

 

I am trailing Prestashop 1.7 and have come across an issue. If add more than one file upload under customisation to the product, when the customer uploads a file to the first, the system automatically adds the same file to the 2nd and so on. Has anyone else come across this and has a fix? You can see it working here:

Thanks in advance.
