Cannot edit objects

Hi, I am using Greenbone Community Edition Version 22.9.1, I was trying to edit a custom portlist (Configuration → Port list), but the button is greyed out.
If I over on the button, I see “Port list is not writable”.
I currently logged as admin user.
How can I fix this?
Thank you!

@Armitage318 clone preset config and edit clone. you cannot edit default port list as it’s read only

Hi, I am not referring to default port list. As I wrote, it is a custom port list.
