Crashes and has permanent change info in iPod contacts

Every time I try to delete a group from within the app it crashes. I cant delete it. The group is in my iPod contacts and I have no way to get rid of it. I even tried deleting the app but the group can not be removed from my contacts. Use this app at your own risk! Ive sent am email to Qbix. Of they help me fix this problem then I will let you know.
