Feral Heart

Okay, so, I have a mass of items. My own made ones, legendary, animal antics, private items, anything I can get my hands on. Yet I seem to have a reoccuring problem. Yes, all my items show up in game but some of them 'dissappear' off of the list. I'll scroll down {To find BullHorns1 for example} and it skips from 'Buck' to 'Chameleion' and its starting to really get on my nerves because some items I'd need to complete a char, yet I can't get to them. Is there anyway to scroll down one by one through the items? Is it a glitch? Can I fix it? I noticed it doesn't happen with the markings, so I though I'd post it here to see if you guys know anything. Thank you so, so much for reading ^~^
