clicking to enter a world loads me into a different world when in the wrong generated world even in

when in the wrong generated world even in creative i can fly through blocks, i can't hit mobs, new chunks wont load or will load randomly if you are nearby them, i can't destroy blocks and inventory works fine. when coming back to the save menu it will show at the top where the recent map played is showed it will show the wrong world

i would add pictures but i don't know how i could show in a single picture the problems but when it happens again (because it's pretty rare) ill try to upload pictures.
BTW- it can happen to other versions of minecraft I don't think it's a version problem
(while writing this i saw that the auto-correct tells me that "minecraft" has grammar mistake seriously?)
