The following Source Value:
{MATH(Add|Double|{TASK(781e1f9d-8808-4239-9c02-a357e4c49647,StdOut)}|0|#0.00)}
With the column format set to:
Order 1: Format: #,##0.00 
                                             
                                        Returns an error below so I assumed column format was only from a file import based on your help doc.
Exception in Task: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

                                         Can you show how you format the columns? It should look like this to get numbers:
