How to unblock FB users? My Block List is empty?

today i played with FB feature to block some of FB users, and i added one person to that list. now i can not access to FB page of that person.

but, problem i face is that it show that block list is empty, with related message “You haven’t added anyone to your block list”.

now i added another person, and list is still empty…

is it a BUG or what? can you help me how to enable access to page of that person?

ok, i figure out where was the problem.

it needs 48 hours to get contacts to be visible on block list.
