Bendy Edges in print?!?!?!

Hello,I have the Anycubic Photon Mono Resin 3d printer, and my prints have been doing this recently. Any idea why? Do I need to replace my FEP or get a new Metal Printing Plate? On a side note I really wanted to magnetic plate attached to my metal printing plate so i can just bend off the prints, but the adhesive that stuck the magnetic plate to the building plate always came undone on the sides and would make my prints look like this too. T_T ( I bought 2 of the BIQU Magnetic Sheets and they wouldn't stick to the plate). Thank everyone. Very new 3d printing person here.
