subdomain mirroring domain?!?!

[Valechumbar]

I setup up a couple of subdomains to my domain lionelmessi.org

but when I go to any of those (en.lionelmessi.org foro.lionelmessi.org) the browser just shows me whats on lionelmessi.org and not the subdomain page. Like if it was mirroring the main domain

Using Plesk, and already configured other subs for another domain and never had this problem

Any ideas?
Thanks in advance

Add domain, uncheck the "WWW" and type in the subdomain.lionelmessi.org, go on and chose physical hosting and set it up and it will point to a new "account" but under the same user (which you chose before you make the domain when it asks you)
