The quest can require to play a room in a certain game mode. The item will be available to win when that room is in the correct one. Depending on a player's level, 5-7 plays might be needed for the right mode to appear.

There are once-off item quests in the game. The requested items are absent in the inventory, because they do not belong to any collection. If you click on 'Hint', the game will show where the requested item is hidden. However, the message might notify that the picture isn't at the right game mode (your second screenshot).

Also there are crafting quests, when the found items must be assembled in the crafting stations. They are proposed by the crafters (forge, inventor, fortune taller lady). Those items will be shown on the top of the shelves at a particular crafting station. They will be frequent, when a player has completed over 4 200 quests (check the TOP100 Seekers to find haw many quests you have already completed).

the following article will provide more details about the quests.
