Subserver is going to the parent domain

When i go to the Sub Server address it goes to the parent domain and shows that website, i have set a record in DNS SERVER, i am not using VM as a NS, i have set VM to create SS own DNS Record, i know it is something silly i am doing i just need to get it all working



Any help would be great i have now tested with one of the other domain and seem to work without a issue so it must be a issue with this domain but for the life of me i cant work it out
