Solidworks DWG export prints transformed sketch

Hello.

Solidworks PDM is automatically publishing our flat patterns to dwg. I noticed on a physical part some extra holes. Solidworks drawing is OK but the dwg conversion has matching holes. Looking into it, the holes came from a transformed sketch under a fold-feature. note, only one of several transformed sketches did this. 

How should I manage this issue so that it will never happen again?
