Blender doesn't follow the coordination of objects. What am I missing? On the left-hand side, you can see that x = 0 and y = 0 but the object is shifted and It's not related to the grid (x-axis and y-axis). It's not in the center. The same issue happens with the z-axis. The object is way above the grid although z = 0 or even a negative value. I think I'm missing something but I don't know what it is.
As @DuarteFarrajotaRamos mentioned in the comments, those values are delta values for translating object. You can access the co-ordinates of the object by selecting the object, pressing the N key and under transform tab, you could see the co-ordinates of your object. You can change them as per your need.
