PlaceholderApi duels doesn't work

[PaulKahleer]

I can't use placeholdersApi from duels plugin in Holographic display i have HdExtension and i can't

I tried use DecentHolograms and also i can't use from ajlb add {placeholder}
I tried use DeluxeMenu and it doesn't work

[PaulKahleer]

Plugin works and in the config.yml
api:
placeholder: true

Fixed, you must change in spigot page the identifier is ''%duel_{placeholder}%
