Question Two Questions About Worlds and PerWorldInventory Plugin and PerWolrPlugins Plugin

Reguarding the PerWorldInventory plugin, for some reason whenever I go back to the files all the code is not there. This might be due to me restarting the server but that should not delete the files? Also, It is not working for the worlds I created.

Here are my groups
groups:

Hub:
worlds:
- DemonicMC
- DemonicMC_nether
- DemonicMC_the_end
default-gamemode: ADVENTURE
Factions:
worlds:
- Factions
- Factions_nether
- Factions_the_end
default-gamemode: SURVIVAL
Towny:
worlds:
- Towny
- Towny_nether
- Towny_the_end
default-gamemode: SURVIVAL

Here is my config:
