bug or me stupid??

Yesterday I could after a long time image again. As I used a new lens and only had 2 hours of imaging time the stack is not the best. However I tried to process anyway.
After “star deconvultion”, I wanted to see if “Asinh transformation” does any good
HOWEVER, when I switched from “auto stretch” to “Linear”, the picture went WHITE !??
I first thought it might only be a glitch but it stays white now?
Any ideas?
I am still on Siril 1.2.0. beta 2

Probably the cut-off cursors were incorrectly set, below the image, set them to 65535 and 0
