There is something wrong with the diode in my schematic or PCB. Please open the PCB at the below link. Press Alt + I or click Design > Import changes. Apply the "change". Now press Alt + I or click Design > Import changes again. Apply the "change". Exactly what has changed? You can spend all day doing this if you like; there's something wrong. Can anyone tell me how to fix it? Thanks very much.
It can be fixed by deleting the component from the schematic and then adding it again from the library.
