FastLogin treating as new account when we add one to /premium list

[og-sketch12]

Hi! I've setup FastLogin (also using AuthMe Reloaded) on my bungee and 2 bukkit servers (hub and skyblock) and when I joined I had different inventory, money, rank, permissions and stuff and when I did /premium, it just treated me as new premium player (the autologin and autoregister parts work fine but how do I make it treat same accounts, I've premium Uuid on true) What steps can I do? Also, I get this in my console

[LuckPerms] LuckPerms already has data for player 'Araxion' - but this data is stored under a different UUID.
[00:35:58 WARN]: [LuckPerms] 'Araxion' has previously used the unique ids [MY UUID] but is now connecting with 'Another My UUID'
[00:35:58 WARN]: [LuckPerms] The UUID the player is connecting with now is NOT Mojang-assigned (type 3). This implies that THIS server is not authenticating correctly, but one (or more) of the other servers/proxies in the network are.
[00:35:58 WARN]: [LuckPerms] If you're using BungeeCord/Velocity, please ensure that IP-Forwarding is setup correctly on all of your backend servers!
[00:35:58 WARN]: [LuckPerms] See here for more info: https://luckperms.net/wiki/Network-Installation#pre-setup

When joined after unpremium myself and this when I first joined after premium:
[FastLogin] Received proxy id: (UUID here) that doesn't exist in the proxy file
