the pivot and anchor in my unity 3D disappeared on the object

The pivot and anchor in my Unity 3D disappear from the object, for example, I have added an image to the canvas and I want to adjust the anchor, it doesn’t exist or doesn’t appear, which results in when I build to Android the image enlarges itself or doesn’t match what I want, so also all UI such as buttons etc., I also experienced problems with my canvas line disappearing when I clicked on another component, please provide a solution
