Problems with Adminland

Hello I tell you about my problem, once I wanted to put the adminland to protect the tradepost area and I already succeeded. But the problem that before that I was wrong and I put it in 4 different areas of the map and now I cannot remove those areas set by the adminland the problem is that now the users let us do anything in those areas and I would like if someone Can you explain to me how to remove those areas, why try to go to the site where it is to remove it and it won't let me. I would like to know if there is a command or some way to remove all those zones.

Thank you very much
