Hmmm. I guess the thing to do is just ignore it ,or trash it if you can. Don't use it or your tama may freeze. Like StarTama said, this happens a lot in the V3 Connection. Just trash the items. If it's a lot of items and they won't trash. I'm sorry but you'll have to reset it. If that doesn't work, you'll have to buy a new Tama. (Last resort. This is very unlikely cause resetting should delete everything.)
My friend once had a V2 Tama. She had the same problem. She ended up buying a new Tama cause it was so messed up. The mistake because it was fed balls, hats, sunglasses, and glitch blocks, her Tama blacked out, and it froze, and then it just blanked.
I know this is offtopic but here there is a LOT of topics regarding this. In 2 pages I have seen about 7.
