Unusual Behavior with Walls

Revit
1

Hi everybody

I’m working on a function for duplicate wall and flip it. But I have one problem with corners. When I run the function the walls dont join. Curiosly, the same function, but writting on c sharp works perfectly. Any suggestions? I share the code and one Photo.

Regards

Solved Flipping the first wall and not the secod.

#For copy Walls.
	direction = XYZ(0,0,0)
	id = ElementTransformUtils.CopyElement(doc,wall.Id,direction)
	wall_wallType = wall.WallType
	wall.Flip()
	walltype_finish= wall_wallType.LookupParameter("Description").AsString()
	
	#For get WallType Finish
	for w in wall_types:
		type_name = w.LookupParameter("Type Name").AsString()
		if  walltype_finish == type_name:
			wall.WallType = w
