Help with Samsung Charge calendar syncing!

[daxelrod33]

I downloaded an app called EboBirthday and sync'd my Facebook account to the app to upload all my friend's bdays. However, the app added everyone's bdays to my calendar as well. So I deleted the app hoping this would unsync everything, but had no luck. I also turned off sync off for the calendar. Any thoughts on how I can get rid of the bdays on my calendar?
