Untimed tasks setting off notifications

Sometimes my tasks will trigger Notification Center notifications even though they're not timed, and once even after it had been completed.

In this folder, you'll find search results showing there's only one task called "Buy domains," the next shows that no time is set for the event, and the last one shows there's no alert set (it defaults to 10:00am but these notifications ocurred before that so that'd be irrelevant anyways).

Thanks for the feedback. It’s hard to figure out the cause since there is not enough info to investigate on this case. I haven’t heard anything like this yet at the moment. I’ll keep an eye on it and will see what could be causing it.

One thing, please search for GoodTask on your Mac and see if you have trial version or any other installs that may cause weird actions. Keeping one application is recommended.

Thanks!
