Permissions not working

[empire_ride223]

I am created a groups. ini and users.ini with the following permissons:
groups.ini:
[Admins]
Permissions=*
Color=c

[Mods]
Color=5
Inherits=Vips
Permissions=core.time,core.item

[Vips]
Permissions=core.teleport
Color=2
Inherits=Default

[Default]
Permissions=core.help,core.playerlist,core.pluginlist,core.spawn

users.ini:
[SomeAdmin]
Groups=Admins

[FancyModerator]
Groups=Moderators

[ImportantPerson]
Groups=Vips

And I'm trying to give home commands (from plugin) and also /help, /spawn and /tpa
The Default ranks cannot even do /help
