"Normal" state ignored in triggers

Hello,

Here's a very simple example that doesn't work : you should see layer "Success" only if you choose states 1 & 3 but it will show as long as you got at least those two selected, ignoring "Normal" state of 2 & 4.

It works if I put "not equal to Selected" as conditions for 2 & 4 but it should work as is, right?

Any clue on what's going on?

Thanks.
