[1.15.2] Config changes being reverted

Not sure exactly why, but in my config I have a list of strings. When I change the config, and reload the config, some settings work properly (things like booleans, and integers) but the list of strings get reverted back to default.
I feel like it has to deal with them being

ForgeConfigSpec.ConfigValue<List<String>>

I can provide more code relating to it, but would prefer to not upload it all.
Any help is appreciated and welcomed
