Licensing Question

I’d like to not show that little bar chart icon that appears when you use a pro feature in the Linear Gauge but when I go to buy the product the site assures me that I need only the free version (for my scenario) and offers a download. When I install the downloaded suite I still see the bar chart pro feature icon.

Am I doing something wrong or is this something I either have to live with or buy a license that is perhaps otherwise unneeded?
