Introduction
What is this?
The decision node will evaluate and execute the paths from top to bottom:
If “Evaluate ALL paths” is not ticked
Once the condition in a path is met, the decision node will move on to the next node and stop evaluating the following path(s).
If “Evaluate ALL paths” is ticked
Even if the condition in a path is met, the decision node will continue to evaluate all other paths.
2 levels of path evaluations

Referring to the above example, if Problem 1 AND Problem 2 are both selected, the above path is FALSE, even though both conditions individually are TRUE.
