Your listing is not set up to show the amount sold.
You are selling them one set at a time and relisting when they sell.
For the number sold to show you need to set it up as a multiple listing with the number you have for sale. As they sell the number will decrease and the number sold will increase.
Sorry I cannot give more details of how to do it but I am not a seller.
