Enhance Preview is garbled

HI anyone there, recently i've experimenting what i think is a bug, whenever i try to enhace an image it seems to make a treshole of colors. at first i though it was just a previsualitation bug, i tried to restart the app and export the image.
also i've install and unistall the app twice. 

if someone had the same issue or can give me an advise would love that.
