Missing document on "CREATE ON STATS"

I want gateways to be added automatically in ChirpStack, when browsing the documentation, I noticed there is a “create on stats” argument in network server:

However, when I clicked the link and jumped to configure page:
There is no argument like “create on stats”. Is there some documentation missing on this part?

also, there is another argument “–gw-create-on-stats” mentioned, but I can’t find any documentation about it.

Sorry, that should have been removed (just pushed a change to GitHub). This option no longer exist.
