Inverted elements occur when the top of the element is now below the base of the element.
i.e. when you link the top of a wall (a high bulkhead wall) to the storey above.
You then adjust the storey height to be lower and now the top link for the wall is below the actual base of the wall.
This may help to explain it more.
