Solved Config list gets emptied when new thing gets added?

I have these three if statements set up:

First if statement (working) (open) First if statement (working) (close)

Code:

if(plugin.getDispensersConfig().contains("." + p.getName()) == false){
                        plugin.getDispensersConfig().set("." + p.getName() + ".dispenser1" + ".id", 1);
                        plugin.getDispensersConfig().set("." + p.getName() + ".dispenser1" + ".cords", Main.LocList);
                        plugin.saveDispensersConfig();
                    }

Second if statement (not working) (open) Second if statement (not working) (close)

Code:

if(args.length >= 1){                       
                        ArrayList<String> allColors = new ArrayList<String>();
                        for(int i = 1;i<args.length;i++){
                            allColors.add(args[i]);
                        }
                        p.sendMessage(allColors.toString() + " < colors");
                        int dispenserAmount = plugin.getDispensersConfig().getConfigurationSection(p.getName()).getKeys(false).size();
                        plugin.getDispensersConfig().set("." + p.getName() + ".dispenser" + dispenserAmount + ".colors", allColors);
                        plugin.saveDispensersConfig();
                        allColors.clear();
                    }

Third if statement (not working) (open) Third if statement (not working) (close)

Code:

if(args.length >= 1){
                        ArrayList<String> allFadeColors = new ArrayList<String>();
                        for(int i = 1;i<args.length;i++){
                            allFadeColors.add(args[i]);
                        }
                        int dispenserAmount = plugin.getDispensersConfig().getConfigurationSection(p.getName()).getKeys(false).size();
                        plugin.getDispensersConfig().set("." + p.getName() + ".dispenser" + dispenserAmount + ".fColors", allFadeColors);
                        plugin.saveDispensersConfig();
                        allFadeColors.clear();
                    }

My problem is:
The first "cords" if statement adds the cords just fine into the config file. Also when allColors get added it works, but then it messes up: when I add fColors to my config this happens:

dispenserconfig.yml (open) dispenserconfig.yml (close)

PlayerName:
dispenser1:
id: 1
cords:
- 28
- 64
- 224
colors: []
fColors:
- blue
- green
- red

I can't get my head around what is going wrong.

It's probably the most obvious thing ever too.

Facepalm.
Told you it was obvious.
I was clearing it after the statement, instead of the beginning.
