Redstone Comparators compare wrong

Initially, the comparison of a single comparator seems correct, but when making a single system that uses 2, it bugs. It's as if one ciparator was comparing the load of another. Previously created logical systems ceased to work.

In the first attached photo is an example of the bug

expected outcome:

system output is off

current result:

System remains activated (loads should be canceled)

 

Another buggy thing in this same system is that depending on the orientation in which it is built, the result is different (as you can see in the second attachment.) (In first orientation, output aways is on if have any power source. in Second orientation, output is aways off)

Please fix this bug, it makes 3 of my calculators stop working (YES, i make calculators)
