Copy own rooms and help

[Nightbringer]

Hi all.
I am trying to learn all the ways of making an escape room and I have setup a puzzle with some candles and it is almost working but I can´t figure out how why the last logical lock is not working as intended.
It is basically two slots connected to one lock that unlocks a light source.

Name Output value Lock Code placement Password
Slot 1 (light 1) 2 Lock 1 (flame) 0 2
Slot 2 (light 2) 4 Lock 1 (flame) 1 4
This one is not working.
If I remove one of the slots and set the password to only one digit it works fine.
As one more test I have added two buttons instead of Slot 1 and Slot 2, and with the buttons it works fine, even with the 2-digit code. But still fails with the 2 slots as soon as it is a 2-digit code.

I-want to share this specific puzzle as to hope someone can help me with the solution but I can´t find away to
And finally is it possible to display the password value next to the input number on locks and the name of the lock.
It is quite difficult to check everything when you have multiple locks and connections.
I have tried to show what I mean on this picture.

Don't forget that type of lock is also matter, because it have different methods to check whole password.
To make it simple - you have 2 slots that connect to 1 lock and 2 different items, right? Items placement is matter?
