[BUG] autoPurge does not work

[ghost]

Describe the bug
autoPurge does not appear in the default config, even though it's on github. Adding it to the default config gives you console errors on start up and doesn't allow the plugin to reload.

To Reproduce
Add the following to config:

autoPurge:
- 1:6

After the server loads, it becomes:

autoPurge
- 66

Details
Please provide the following details about your server set-up:

• Spigot version (found by running /version): Mohist 1.12.2
• BetterTeams version (found by running /version BetterTeams): 4.2.1
