It seems like its a loose aperture ring. If i squeeze it or put enough pressure on the ring it sticks to 1.7 if not it goes back to 2.5 even tho the ring is on 1.7 settings

Help needed. I am not sure why this is happening but I cant seem to set the aperture to 1.7 from the dial on the lens. It would always display as 2.5 on the camera. It works when i have it set to 2.8 or 2 but whenever i set it to 1.7 it just display as 2.5. I am using it with a GFX 50R. I tried it in all modes. M and A. I really dont know how these electronic lenses work. I am new to Fujifilm coming from all manual rangefinders and this is really frustrating me. Thanks in advanced.
