Math formula (Multi Column)

Hi there!

I have a problem using different formulas for two columns using the “Mathformula(Multi Column)-Node”.

Can anyone explain to me why I get as an output two times exactly the same column (with wrong values), instead of two columns with the correct output for each formula?

If I put only one formula in the table, the output is correct (for each formula). but when I try to put the two formulas together, it doesnt work anymore.
