Same issues with me…only it took me a little bit to notice it. Now have social shares going to multiple permalinks and am probably confusing the heck out of Google. Not good for SEO. Not happy.
On edit … conflict with another plugin. WPCompear. This is not the first plugin WPCompear has had compatibility issues with. It’s going and category permalinks is staying. I’m tired of messing with it (WPCompear).
