EssentialsAPI getNickname Warning

[Nuke552]

Any time someone uses faction chat on my server (faction, ally, enemy, truce, ally-true) I get this warning message in console with it:

[Thu, 13. Jun 2019 10:38:25 EDT WARN] FactionChat's EssentialsAPI getNickname method was called when it shouldn't of been

This isn't a pressing issue, just an inconvenience. The plugin still works fine, but this message flooding my console has just gotten slightly annoying. I've tried just disabling the Essentials useNickname in config.yml, but I still get the message. Any help in fixing this would be appreciated. Thank you
