Gen Image cropping to size of thumbnail Beta 27.0.1

Gen image is cropping the output to the size of the square thumbnail that shows on the right side window after you make choices for style, comp, etc.  The active image, style and comp ref are all the same size 1024x280.  I'm using PS Beta 27.0.1.  I quit and restarted PS but problem persists.

thanks for any help.
