I have just tried, and I see a bug in the print size (the default value change), well done
When I launch image resize, and put your values 22x11 inches with 350 dpi and apply it, I have an image size (in pixel) of 7700x3850 px. Do you have the same value?
If I open again image resize, I have the true value
in pixel but not in print size because by default it's in centimeters and 150 dpi...
For that reason if you enter 22x11 inch / 350 dpi your image won't change because it will be exactly the same size in pixel...
For the moment you'll have just to see if your size is alright in pixel.
We'll fix it!
