Mapping data flow does not load any rows to 1 out of 2 branches

Cedersved 16 Reputation points

I have this mapping data flow, with two branches from 'RemoveHdlColumns'.
When I run this the rows from MergingInput is only loaded through the bottom branch.
All the rows are loaded for the 'Select2' transformation, but NO rows hits the 'Select1' transformation (or HashAllColumns or ChangedRows).
Select1 and Select2 are identical, without any expression - just set to auto mapping.

Why is this?
