How to make UI position(coordinate) equals to world coordinates. Please help!

Good day!

I’m struggling for days now with this problem. I’ve googled so many possible ways to fix my problem and i think this is the right time to ask here in forum. I’m developing a casual 2D game where you tap monsters to kill them and you have some items to use to kill them. The problem is when i drag the “item” it’s so far from “world”. The item is an image in Canvas which you will drag and drop to monsters to kill them.

Here’s an image that will explain more.

When i dragged the skill.

And now it’s position.
