Server showing me gamemode changes from other players when using F3+N

[Chrisi06]

Hello,
my server is showing me the gamemode changes from my other friends even though I've installed EssentialsX, EssentialsX Chat and EssentialsXSpawn. I've never had this problem while using the plugin before. Weird is, that those gamemode changes are not being shown when manually typing in /gamemode 1 or 3 in the chat but when using the shortcut F3+N.
Already, thanks for your time and help!
