Applying cropping + resizing on a canvas make jam out when trying to use brightness, contrast etc...

When applying croppping + resizing on a canvas, it's impossible to use brightness, contrast... etc ...
Following (I think) the procedure ... there are two images displayed ... background: the good image (cropped and resized) and the foreground is the entire image, but jammed.One thing... when the cropping is seleced fom the left side of the canvas, I can see the 2 images as shown on the attached images

Any reason ??
Thanks for an answer and ....great job !!
