[Plugin: Pricing Table] Nice plugin. Feature/unfeature issue

Hello
This is very good plugin with potential to be perfect.
I have problem with feature/unfeature, don’t know is it a bug. Once column is featured it cannot be unfeatured again. I’m able to switch and make another column featured but it’s not possible to make all columns unfeatured. Workaround is to create a new column, make it featured and delete it, but it’s a crappy workaround 🙂 Is there solution for this?
