Something wrong with /clan ff and /clan globalff

I'm using paper-282(Worldguard, and some other plugins,that doesn't affect at simpleClans).
Minecraft version 1.15.2.
Command globalff and ff doesn't work properly.
When i try to allow or deny globalff i got a message: usage /clan ff auto/allow"

Here is the message bellow (I'm using russian locale).

The same message i got when enter "/clan ff allow" in game.
Am i using this command incorrectly? Or it is a bug!?

/clan globalff одобрить
/clan globalff авто

/clan ff одобрить
/clan ff авто

There are two problems here:
"auto" and "allow" were translated only in one place.
The globalff command is getting the usage of the ff command.
