The IT of Swiss leaves a lot to desire , under modify for passengers it shows first and middle name combined, so I added my middle name and deleted my middle name from my first name, result is that I now have my middle name duplicated and there is no way I can edit it.

Also home address and destination address once entered default to destination address , even though two different addresses should appear, another thing that you cant change after modifying.

Swiss really how idiotic, don't let passengers modify fields if your IT is in such a poor state, I now have incorrect information in my name and home address.
