VIP Max Skill Points Not Working

VIP skill points are not working correctly.
As a result, VIP players have the same 300 point limit as normal players.

Current configuration:

"General settings": {
"Skill points per level": 3,
"Modified skill points per level based on permissions [must be higher than default]": {
"skilltree.points.vip": 4
},
"Maximum points a player can spend [default]": 300,
"Modified max skill points based on permissions [must be higher than default]": {
"skilltree.vip": 400,
"skilltree.nolimit": 200

Even though the VIP permissions are configured, they do not take effect.
VIP players are still limited to 300 maximum skill points, the same as regular players.

I overlooked it and forgot to upgrade the version. Thank you.
