Auction feature selling price does not work, stack size does not work, and partial stacks does not work

When I am setting up my auction bought the purchase portion works as intended but when I set up selling portion I have to set selling price to 1/40th of what I want to sell per item. IE if I want something to sell for 1g per I have to set it to 2.5 silver per. When I set it to sell a stack of 10 it creates the stack of 10 but then is unable to find the item in inventory. Also if I set sell partial stacks it does not work. I am on a TBC private server.
