Free Version of this plugin

So question on the free version of this plugin. Does it work as a wholesale plugin with out purchasing the pro version? I installed and it gives ALL products a discount regardless of the role. Log out, price still shows the discount.

When I chose “Discount By Category, Logged-in-Role,Product”, it gives all products a discount. Am I missing something?
