Adding more than one instance doesn't work as expected

[Grayda]

I'm putting two of these on my dashboard page (e.g. one for users, one for product vendors) and when I do, picking a file for the second box puts it in the first, and picking a file for the first box puts it in the first.

A quick glance at the page's source suggests that the input's name HTML attribute is the same across all instances, there's a conflict going on there. Perhaps making a unique name for the field would work, such as name_product_vendor?

EDIT: Steps to reproduce:

1. Add two instances of this card to the dashboard (or resource page)
2. Click on "Choose File" on the second card and pick a file
3. The file you picked appears in the first card, not the second.
4. Expected behaviour: File you picked appears in the second card.
