Config file changing automatically?

Hey guys, my plugin has a config file, and one of the fields is an item id. By default, this id is 322, however I made it so that a person can add byte data to an item (ex. 322:1). However, once I do this and reload the plugin, for some reason 322:1 changes to 19321. I don't understand why this is happening, can you help me?

Heres my config init:

Code:java

        config = getConfig();
        config.options().copyDefaults(true);
        saveConfig();

 

Remove copyDefaults. It overwrites the config on the disk with the one in your jar.

 

Doesn't matter if I do that. Whenever I reload my plugin it converts it to a number. It happens with other numbers and values too.

 

Is there any other code getting/setting values in the config?
