When I log back in to my world, my old items are there.

There was a point where I logged out of my game in a certain place in my world with certain items in my inventory and ever since then, every time I log out of my game and log back in, I spawn in that someplace with those some items in my inventory, no matter where I was or what I had in my inventory when I previously logged out. The strangest thing is the blocks I placed saves. All my structures were exactly as I had left them, I just spawned with my old items in my inventory and in a different spot in the map where I had logged out of my game ages ago. I haven't been able to figure out how to fix it. Thanks.
