I am seting up a website using the community edition which intend to upgrade to pro.
I see that some product features variants appear while other dont.
Any idea what to do ?
did you already assign the features to a product? 
Yes of course. The feature which is “COUNTRY” appears as a title. But the Variants like “Sweden”, “Belgium” etc not always appear.
Screen shot or some idea of your setup and the displayed results?
Might check your settings in config.php I think it was or maybe in the actual Csc admin settings. I had a post a while back about some features not showing and I recall it was a setting bug somewhere.
