Inventory problems

There is a problem. As first, I have problem with Inventory. I don't know why, but I don't have a half of Inventory, it won't show me items and when I search it doesn't show anything and I can't click anything. As second, it's moved aside a little bit where my armor is so I can't even click it. And thats the bug that it's moved aside and I can't grab it from over there. I hope you understand what I'm trying to say if you don't it's OK. I just wanted you to fix that issue with Inventory.
Thank you,
BYEEE!!!!!!
