I have relisted a unit earlier and changed the starting price, however it still shows the first price?

This old amount you see on your dashboard represents the unit's original starting price. On the front end, it’s listed at the new starting price. Once a new buyer places a bid, the old starting bid will be updated to reflect the new starting price. 

This helps us maintain a record showing that the initial price was not accepted by the market the first time, leading to the subsequent reduction.
