Hi Stian,
Thank you for using WEBENCH and taking time to provide feedback. Issue 1 of bottom-left winding polarity is now fixed, schematic is adjusted and now available for you to try. Issue 2 that you are seeing might take a little longer to be fixed. However, it is the Voltage Shunt Regulator image that is getting masked. This schematic should have looked like what is in the attached image. Note, that inside the BOM This component is represented by VR and LMV431 or an equivalent component.
Please let us know if we can be of further assistance.
Best Regards,
Pavani Jella
