Prints don't fit together

Hi. I am quite new to resin printing. All small prints have been nice so far but as soon as it comes to bigger pieces, they don't fit together. The resin seems to change it's form.

The print is from lord of the prints and the small ones were amazing. Even the smalles details where great. But now with the bigger piece....

The problematic pieces are closer to the print platform with supports on it. Could that be a reason? They're pre-supported

Printer : Anycubic X6KS Resin: Anycubic 3D printing UV sensitive resin basic in grey Settings: Bottom layers 0 (the print comes with a bottom layer) Exposure off 0.5 Bottom exposure 20 Normal exposure 2.5 Z lift distance 8mm Z lift speed 2mm/s Z lift retract 3mm/s Exposure off compensate open
