Honestly this is only because they made a bad survey. A ranked choice is better.

Lets say you have 5 choices. You give each choice a voting weight of 1 (not an issue) to (5 biggest issue). You only get to pick a weight once.

So in this type of voting even if everybody put error handling and #4 it could still win by a large margin if the 5 values were spread out over other concerns.
