Jquery UI Draggable Position Issue

Jquery UI Draggable Position Issue

Good day.

I am currently working on a functionality wherein you can drag a div and place it in a div. It is almost similar to this  Card Game.

I have worked on it and I was able to run it, but when I integrated it to the main application, it is no longer working.

Draggable is working since I can see that when I drag the div, I can see the dragging class.
the reason why it is not working is that, when I drag it.. it does not move.. the top and left position is not updating. It is in just the same position where you started to drag it.

What could have caused this issue?

Thanks in advance.
