This is the first time I’ve used HDRP, and when I try to add a canvas, I get something weird.

When the canvas is in the scene screen, if I touch the canvas or a child object of the canvas, the canvas becomes smaller than its normal size and I can’t see it when I switch to the game screen.

But there is such a strangeness that when I switch to the scene on the game screen, it returns to normal again.

When I select the text on the game screen and try to change its position, it shrinks again.

When i click canvas or any children of canvas

What is causing this? Are my settings wrong or something else?

Thanks.
