SPAWN IN ANOTHER PLACE WHEN I ENTER THE PORTAL

This happens in all versions but I didn't find an option for that, sorry

I created a portal at my base and it is already the second time that when I come back from nether I go back to a random cave! this has already happened in another world (and it remained there until today with this bug), and something that the two have in common is that I optimized them. Please fix this bug PLZZZZZZ
