Comment 1 for bug 406214

It's the behavior of 'All values'. As it's the same behavior than before, I am pretty sure: if you unselect All values and doesn't select anything else, All values is selected back, so it display everything. It's the same behavior than the fields 'FOI Topics' or 'Author Email Addresses'. So I added back that 'All values' option, which basically is there to look like those two others fields, but doesn't do much better than selecting nothing in that list.

It's updated on istos.
