How can i delete ports that i dont need?

[teominiatis]

Good day to all,

I would like to delete some ports that i do not need inside the game.
With the previous txt format i could delete or edit any port but now with the xml format even if i delete a port it apears again in game.
It hapens also if i start a new game.

Thanks in advance.
