Basically i got pex a few weeks ago, i got essentials first, and it was working fine. I am running a 1.10 server. The default rank had a prefix and the perms were working. So did all the other ranks. Now when a person comes online that is default all tha they get is a <playername> with no prefix and no permissions. Its like I havnt even written config for default. All of the other ranks work with the right perms and a prefix. It is just default. I know that my pex config is correct because i put the permissions.yml config into an Online-YAML-parser and there was not one error. I thought that it may be to do with essentials but i cant find anything wrong so can someone please tell me how to fix this.

This is the pex permissions.yml config:
