[Keary VS]

I have noticed several times after adding several collection items to my journal that the "Add" button disappears and will not allow me to add the item to my journal. If the item is used in multiple collections like a "weathered bone" the second one will have the "Add" button but the top or first one will not have the button. This has happened a few times now and i cant find anything to allow me to fix it in game. It will fix itself if i camp out and come back. Any ideas here?
