When you have 5 limit orders for a stock, and you want to change the limit price by clicking replace, system won’t allow you to do so.
Note that this is not trying to add a 6th limit order, by just to change the limit of the existing 5 limit orders. System won’t allow you to do even one price limit change on any of the 5 limit orders. I believe this is a bug.
