As I've gone around Azeroth collecting Coins of Ancestry for the Lunar New Year event, I've noticed that each Elder is Given three "items" in the zone's sub-list. The Quest, the Elder and their particular Coin of Ancestry. I get the first two, but when I hand in the quest and receive the Coin of Ancestry it remains at 2/3. The Coin in the sub-list remains a diamond icon and doesn't change to a tick. I tried refreshing the collection but no change. It means that the event has some 84 things (84 coins of ancestry) which you can't collect. Any ideas?

I believe this situation should have been fixed in 01cc9e3.

'Cost' Items were still being considered collectible when nested under completed & repeatable groups (such as yearly quests) which would cause them to continue to show even once the quest was completed on a given character.

Actually I've just noticed that if you show the Lunar New Year Holiday in the main list, it shows the coins you have collected that day as 3/3 (yay!) but not the coins I collected yesterday (they're 2/3). I tried to refresh the list and all of the 3/3 coins reverted to 2/3. ATT obviously can't distinguish between individual coins given by each Elder and only adds those coins to the main list as you collect them. I doesn't seem able to keep this data however. When you next log on the collected things have disappeared. Maybe just delete the coins in each Elder's subfolder? It's frustrating to lose your progress like this.
