Expected Behavior

Creating a NMOS/PMOS pcell using the provided klayout Pcell generator I expect to get a symmetrical device.

Actual Behavior

The device is non symetrical on Metal1 layer with a 1um offset.

Steps to Reproduce the Problem

Insert a NMOS/PMOS device. Choose which type 3.3/5/6 any one of them has the issue. Choose the desired width and length. So far all tested width/length combinations have the issue.
