Minecraft nether PortalBug?

I'm playing minecraft with a friend and we have built a nether portal and whenever we come out we spawn on a broken portal we have also dismantled it and there's always a new one there please help me thanks in advance

Try to link your protal with one in the nether, how it works you see

PS: Your question is very confusing, but try to write precise sentences that are not too long, so there's less misunderstanding.
(Because I'm not sure I understood the question correctly)

Is not the topic but do you already have a broken voice? I'm 14 and I'm not yet or only at the beginning
