When I give a drop shadow to a shape in illustrator, the shape's border lines grow and change.

Hi, when I apply a drop shadow to an object in Adobe Illustrator, the object's frame reshapes according to the drop shadow. The object's dimensions are distorted. It looks like the object is expanded along with the shadow. But I don't do anything like that. The object's borders don't change when I preview. This happens when I apply the drop shadow. How can I fix this?

I used translation. I hope it's understood. Thanks.
