Hey Jose, this was fixed quite a while ago. Is this still an issue for you? Please reach out to me at TreKingApp@gmail.com for support and I'll be glad to help you out.

What’s new

New: Support for canceled ("ghost") buses.

Predictions for CTA Buses that have been canceled will now show a message indicating as much and the time it was supposed to arrive, so you don't sit around waiting for a bus that isn't coming.
