Stunning Charge

In the short description for Stunning Charge it says polearm, but in the helpfile there is no mention of Polearm only, but just mentions charge. Should either the helpfile say Polearm only, or if it works with Spears, should the short description remove the Polearm part. I apologize this isn't a bug but I wasn't sure how/where to post this. Thank you for your time!
