arcpy.SmoothPolygon_cartography not working as expected

Hi guys, 

 

I'm having some troubles with smoothing polygons in arcpy. It works well in ArcMap with exactly the same settings but when I use "arcpy.SmoothPolygon_cartography", the polygons are not smoothed, as shown in the images below:

I have attached my code, the original shapefile, the result from ArcMap, and the result from arcpy below. The result from ArcMap is exactly what I want but as I have over 1000 shapefiles to process it's not practical to do it manually in ArcMap. 

 

Also I found this bug: BUG-000117346: The Smooth Polygon tool does not smooth the polygons.. 

However, I was using the PEAK method. 

 

Any help would be much appreciated.
