K8091 alarm problem

Hey, I just built this alarm clock that I bought from you as a project on school, I took it home to test it out.
It works great, the time is right, the alarm buzzer works, and the light works aswell, but one thing I havent solved out, how do I deactivate the alarm? No matter what button I press, or deactivate the alarm in the time set menu, it goes over to sleep mode and buzzers again after 8 minutes, and only way to deactivate it for the day is to drag out the power of it.
Is it something wrong I am doing, or is the circuit wrong somehow, I don’t know.

Thanks.

Normally button two (in the middle) is for cancelling the alarm.
