In a Graphical Calculation View i created 2 calculated columns on the same projection-node.
One Column uses the result of the first one.
However the result is wrong.
I noticed that the 2nd column uses SQL engine and the first column uses Column Engine.
Is this a known Issue or is it an unknown bug?
Calculated column:

SQL result:

Also: Why is Column Engine the default engine for calculated Columns?
(I have trouble aggregating columns with null values and therefore switched to SQL)
If I remember right SQL Engine is also faster. So why is Column Engine the default for calculated columns?
