Luminosity problem with leaf capture 11.5.1 64b

Greetings
I'm the lucky owner of a second hand Hasselblad 555ELD with a Leaf Aptus 22 back.
I use Leaf capture 11.5.164 bits with my macbook pro.
I shoot in uncompressed .Mos
On the screen, the luminosity is fine (like what I wanted). But when I save the pictures (to.mos) to post prod them on photoshop and camera raw, the luminosity is darker and I can't work on them.
When I save the pictures on ttif or jpeg, the luminosity is fine. But i want to work on raw format.
I have tried to take pictures with a memory card (without using leaf capture) and post prod them on camera raw : the luminosity is the same on the numeric back and in camera raw. The problem is I must use only the protrait format because of the width of the battery and the motor of the 555 eld.
Have I done something wrong with leaf capture?
Thanks for your help
