Not shure if this is a bug. Sometimes the expression node does not seem to work. I created two expression nodes with different logical expressions. Although one of them seemed to work fine, the other one simply did not response to any input changes.
I then simply copypasted the working node but even this one does not react to any input changes (as you can see in the picture)
Did I do something wrong?
Thank you in advance!
