Solved Replacing Values in the config.yml

I'm trying to replace a value in my config.yml. How would I go about replace the REC with something else? Here is what my config.yml looks like:

Code (Text):

Ranks:
  2a1599da-2b4c-4328-9a33-5cc62e7d031b: REC

I'm tried doing this, but tit just add that same thing again with my new value:

Code (Text):

 getConfig().set("Rank." + uuid, "PVT");
 saveConfig();

Code (Text):

Ranks:
  2a1599da-2b4c-4328-9a33-5cc62e7d031b: REC
Rank:
  2a1599da-2b4c-4328-9a33-5cc62e7d031b: PVT
 

 

I really need to look through my code more carefully xD Thanks for pointing that out!
