Items from BLTC Chests after Mar 16 Update
If they have different labels, they probably are actually different items
You can test this by linking the item in chat & prepending with ‘/wiki’, e.g.
/wiki [Tome of Knowledge]
Even if the wiki doesn’t have the items linked, the initial page that pops up will show the item ID.
This, unfortunately, isn’t a new problem. You are probably aware that there are already (too many) items with identical names that don’t stack, because they are actually different things (sometimes with identical mechanics, sometimes not). I expect it to keep happening until ANet appoints someone to be responsible for ‘change management’ for the game’s naming conventions and item inventory.
