Items that are not actually collectible (NPC shop items) give you an error when attempting to collect them that report the text below.

"You cannot collect items that are purchasable via the NPC shop."

This is completely fine, but why do they have an (X) in the "Collection" section when quick-viewing the item? If this is a bug, please update these items to say "Not collectable" just like food items instead. Just so we are aware what is collectable and what isn't.
