portal to the broken nether

Good morning, mojang team, I just reported an error regarding the portals to the nether, today I was preparing to create a new portal on the side of my house and everything was going well, enter the nether correctly, only the failure comes here. .. I was preparing to return to the normal world to leave all my inventory at home but the portal through which I entered the nether sent me to a very distant place where I had an old portal linked, well I thought this is normal because it still existed , but here the strange thing is that when I realized that I broke that old portal that I had and left the new serca in my house. To my surprise, when I returned to my new portal when I returned, it still appeared in my old portal when I was no longer there. I removed everything ... and thus countless it is generated again, and therefore the obsidian is infinite and I cannot use portals correctly when I return from the nether ... I hope to have explained my problem and it is the right place for this problem, too I hope this can fix it soon, the game is very good regards
