After slicing the STL file in Slicer, the object becomes distorted.

I tried to explain this in the attached images. I designed an object and sent it to Creality Print as an STL. In the preparation screen, the object appeared perfectly smooth. When I sliced, I indented part of the top part of the object and added supports there. After the object was printed, the top and bottom parts broke off because of these supports.
Is there a setting for this in Slicer?
