Re installing auto pot

Hi, I tried setting up my AutoPots with soil, but since the pots are 4L, I decided to switch to coco coir and Sensi Bloom nutrients. When removing the soil from the AutoPots, I noticed that the roots seemed to grow into the AutoPot system. I have an air pump, etc., but I think I used the wrong papers in the pot. I placed the shiny golden paper under the pot. Should the golden paper be inside the pot instead of the grayish fiber paper?
