to clarify, i also had all the achievements for completing the separate delves including the Loth'Na Caverns but was not awarded the Upper Craglorn Cave Delver achievement where the Loth'Na Caverns were shown as still missing. i kept going back from time to time to kill the boss again but nothing changed.
the other day i did the Gray Passage pilgrimage quest which takes you to 6 delves in upper craglorn, including the Loth'Na Caverns. after completing the quest i was awarded not only the Craglorn Pilgrim achievement for completing the Gray Passage pilgrimage quest within the alloted time limit but also the Upper Craglorn Cave Delver achievement and the Upper Craglorn Master Explorer achievement.
hopefully that works for those of you that still have issues with those achievements as well!
good luck
