I did not customize the menu/action
please see 2nd screenshot... it has filtered links to be restored or to be cleared from bottom menu, but it cannot be cleared from 3 checkboxes, because last checkbox is inactive... as you can see at 2nd screenshot...
it is not a problem, links can be cleared from bottom menu, but I was wondering why that checkbox from 3 checkboxes is inactive...
if you have time, better to focus on
