Leaf Aptus-II 12 Color Shift PROBLEM

Hello! I have a problem!
When shooting at shutter speeds longer than 1_125, the image is covered in green, which can not be fixed.
At exposures shorter than 1_125, the color becomes poisonous purple. It too can not be corrected.
I work in a photo studio, and the optimal exposure for me is 1_125, but I want the camera to function 100% and I did not have a headache about it.
What could be the problem? Help, please, with advice!
I can do a test survey on all exposures, ISO and apertures for clarity. I really need to solve this problem.
Thank you.
