Mask gets deformed when copy adjustment layers with a mask from RAW to a TIF file

Hello everybody,

I stumbled across a problem with adjustment layers and their masks when I copy and past them from a RAW (.nef) file to a .tif file.

So here is what I wanna do:

I edited a bunch of photos as nef's in C1 and made variations and different moods.
Then realized I have to retouch some stuff in PS, so I stepped back to my basic edit and converted the Original nef into a tif and sent it to PS. After retouching I wanted to go back to C1 and copy the adjustment layers from my nef Variations on my retouched tiff file. But suddenly every mask I did on the nef Variations is somehow tighten vertical!

First I thought this might be a crop issue, but as my example below shows, it's not.
You can see on the left is the nef, with an adjustment layer that has a perfekt circled mask. I coped it on the tif file (right image) and the circled mask got smashed. 

Am I missing something?

Appreciate your help.
Kind regards!
