A16v3 cannot use multiple digital output on one load?

Hi. I have bought your A16v3 and install your KCSv3 on it. I am making a Door entrance and alarm system for my shop/house using your A16v3 board with Home Assistant. For now I test with one door and one buzzer, later I add more door window sensor.

I am trying two different digital output setting for one buzzer. Meaning I connect two digital output wire to one buzzer as shown in picture above.

I use DO1 for alarm sound. When night time and shop is closed, if someone open the door, the buzzer will turn on continuous.

I use DO2 for notification beep sound during the day, when shop is opened and customer open the door it will play a short beep. Because I want a short beep, i set it to delay with 3x100ms.

When I connect the board as shown in picture above, the KCSv3 become buggy. It become slow to load, freeze or crash and not responding to click. And when it on the buzzer in IFTT or Home Assistant automation, it doesn't follow my setting as above, it just on for two or three seconds then it off. I have to factory reset the board to make it ok again. If I connect only one digital output to my buzzer, it work OK. 

So does this mean I cannot connect two digital output to one load? I have to use two or more buzzer and connect separately for each different type of programming?

sure, two OUTPUT line can't connect together. you can create two different IFTTT command, let one OUTPUT do different actions.
