Strange shapes in the sky

Hi,

I would like to ask for an advice nad solution for my Photoshop problem. When I compose panorama with blue sky a wierd shapes occurs in the sky when I set high dehaze and low brightness to check the dirty spots of the sky. Every single photo of such panorama is absolutelly clear with no shapes. Problem occurs only when I try to create panorama from selected photos. Can you please tell me what causes this and what to do to avoid this?  Thank you in advance.

P.S. those lines are  not the effect of the monitor and high resolution. It is there even when zooming.
