Default names not in configuration
The default configuration does not provides 500 most popular english names.
i have been wondering the same, lol
The entire default configuration is not shown on the plugin page, it is generated under oxide/config. The documentation has it truncated to not waste space.
The default configuration does not contain the names, not in the plugin page or in real life :P 
They are not there.

Merged post

even tho they are stated in the plugins json, they are not in the config when you first load it.
But as i said, the names can be found in the plugin.json
Could you provide what is there on first load?
This is what I had on first load:
{
  "BanditTitle": "bandit",
  "LogInConsole": false,
  "LogInFile": false,
  "MurdererTitle": "murderer",
  "ScarecrowTitle": "scare",
  "ScientistTitle": "scientist",
  "SurnameList": "Smith, Johnson, Williams... 500 most popular enlish names",
  "UseFirstNameFirstLetter": true,
  "UseTitle": false
}​
Are you sure that wasn't copied from the plugin page? That configuration is physically impossible to be the default, generated configuration, being as "500 most popular enlish names" isn't physically in the plugin at all.
i had the exact same config when i started xD i have no clue how its possible..
Are you using a host that provides a premade config vs. generated? Some do that.
Downloaded straight from Oxide
Unfortunately, still physically impossible. All versions of this plugin on our site do not have "500 most popular enlish names" in them at all, so that confiruation cannot possible come from this plugin, only if copied from the plugin page. I would suggest deleting the configuration and letting the plugin recreate the actual defaults.
Deleted config file and let it generate a new one. 
This is what was generated...

{
"BanditTitle": "bandit",
"LogInConsole": false,
"LogInFile": false,
"MurdererTitle": "murderer",
"ScarecrowTitle": "scare",
"ScientistTitle": "scientist",
"SurnameList": "",
"UseFirstNameFirstLetter": true,
"UseTitle": true
}
Reproduced this. Will work on doing some fixes for the plugin.
It is in the cs file. (line 268).
