Banding on RAW Image

Hi,
I wonder if anyone can help. On some RAW images shot with Z8 I am experiencing sever banding when viewed in PL. The same image is fine viewed in PhotoMechanic and NX Studio. I attach screen shot.

Any Ideas ?

What is the format of your RAW ?
All RAW formats of the Z8 aren’t supported.

Raw recording : Lossless comprtession
Image quality : RAW
