Without being able to see the listings, it's impossible to say what the charges were for or to speculate why they were removed.
Look in Payments to see if you had promoted the items or if the charges are from a previous sale, refund etc.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
