If you don't have time to figure it out, it's okay. Since I didn't have much content, I went ahead and uninstalled and reinstalled and it fixed the problem.
I just ran into another bug. In the Notifications setting, the checkbox for Question and Answer plugin looks like this "qa+email_notifications_setting_answer." I tried to look that under Language settings in the admin, but can't find it. Do you know how I can fix this? Thanks.
