this isnt a bug, the mechanics are designed to do that. I dont know the math but when you make a new portal in the nether and the multiply x*8 y*1 and z*8 then it will go to that exact (or closest) in the normal world
This has happened to me, it is more of a problem with slimes though. I think mojang messed up the hitboxes on big slimes during an update because now they are merely impossible to hit
