Why are some of the commands shown in bold letters?

Some of the "Allow"-commands and some of the "Remove blocking"-commands are shown in bold letters. What is the meaning of it?

IIRC in the main menu the bold site is the site you're on, in the Recently Blocked Site sub-menu the bold sites are the sites that have been blocked on the site you're visiting

Thank you for your help, barbaz!
