When you don't have enough food for treasure hunts it picks all the things, even apparel items already on wolves, companions, moonstone shards, breed changes, and trinkets
I came to post this issue as well. It happened to me (playing mobile) too. I did have enough food points, but the auto fill decided to use almost everything but food. I took a screenshot as well, but I'm not in a place that I can upload it, at the moment.
