I hope I picked the right project this is for but on the Nintendo Switch Minecraft version I am having a problem with my nether portal. When I enter the portal at my house to go into the nether everything is normal but when I exit it a new portal is spawned behind my house in the middle of the ocean. I have tried breaking all of them and trying again (at my house,  the nether,  and the new ones) but always have the same result. It doesn't make the glass breaking noise- if it still does that- it's been bugged for so long I don't remember anymore.  I don't have cheats on or any mods, just the plain game. I have attached pictures from my house and where the new portals spawn. Thank you.
