Hello guys i cant figure out how kits work i wanted only One kit but if i change It on config , i keep only getting now kit

hi, I don't understand. what is "now kit" ?
if you want to use kits then put them under the "Kits" section in the config.

    "Kits": [
      "kit_1",
      "kit_2",
      "kit_3"
    ],
    "Kits Least Used": [
      "kit_4",
      "kit_5",
      "kit_6"
    ],​
