says it requires criteria 19484, 19485, 19486, 19487, 19114, 19488, but when we go to
they have the achievement but they're missing all criteria for it

Also, there are no "checked" criteria for that achievement on official Armory:

While we're on the same topic, some old guild achievements are displayed with the similar error:
achievement is complete, all bosses are killed but Nefarian isn't checked.

Thanks for pointing this out. Added to known issues and opened a bug report internally.
