Need Help With Objectives,PlaceholderAPI, and scoreboardstats.

Code:

# Main configuration

# Compatible mode for other plugins like HealthBar, ColoredTags, GhostPlayer, McCombatLevel, etc. ......
# or the vanilla scoreboard
# In case you miss the log message: this option requires the plugin called ProtocolLib
# This option will work around the Bukkit API and will send raw packets
compatibilityMode: true

# Should be the node disabled-worlds handled as whitelist or blacklist
disabled-worlds-whitelist: false

disabled-worlds:
  - city

Scoreboard:
  Title: '&6&lStats'
  # seconds
  # For instant updates you can or 1 and it will update every second
  Update-delay: 1
  Items:
  # The Title must have under 48 characters
  # Title: Type
  '&9Online': '%online%'
  '&AMoney': '%money%'
  '&9Ping': '%ping%'
  '&CHealth': '%player_health%'
  '&CLevel': '%player_level%'
  # Your can choose your custom score here
  '&1MagePoints': '%objective_score_MagePoints_Dummy%'

# Let ScoreboardStats track stats (kills, deaths, mobkills, killstreak) You need no plugin for this
enable-pvpstats: true
Temp-Scoreboard-enabled: false

Temp-Scoreboard:
  Title: '&a&lTop Kills'
  # %mob% | %kills% | %deaths% | %killstreak% | %kdr%
  Type: '%kills%'
  Color: '&9'
  # How many Players would be displayed
  Items: 5
  Intervall-show: 300
  Intervall-disappear: 300

So that is the config for my Scoreboard-Statistics. Every title works fine until I put in " '&1MagePoints': '%objective_score_MagePoints_Dummy%' ". Then everything using placeholderAPI breaks, giving me a value of -1. I'm trying to link my ingame dummy objective named "MagePoints" to scoreboardstats sidebar. Any tips?
