Hello @petmro,
seems configuration from Table Manipulator regarding included (filtered) columns is not restored when opening workflow with 4.3. version. That causes duplicate column names. To fix it you only need to check (include) SAS Date Start(shifted) column.
Additionally I have opened, configured and exported workflow with 4.3.3 which you can give a try.
