Add a store with a buyer reputation of at least 2 hearts to increase the number of added stores. If the other party's buyer reputation is less than 2 hearts, even if they add your store to their favorites, the number of added stores will not increase. Only when the other party's buyer reputation rises to 2 hearts, the number of added stores will increase. If you don't have a public collection, you can't see it in the collection column! If you want to add items, the store seems to be useless!
