Does it show up if you do "wallet_account_order_list" in the console?

If so, you should be able to copy the ID and do "wallet_market_cancel_order <order_id>"

I had a sell order in bitSILVER which I cancelled. It did disappear from the "Sell BitSILVER Orders" list, but it is still in my Open Sell BitSILVER Orders as an active order, and when I click on "Cancel"  it just says "cancelling" but nothing happens. I have tried restarting the wallet with the same results. The bitSILVER do not show up in my Account Balances, and bitSILVer is still in my Open Sell Orders with the "Cancel" button back, but not in the "Sell BitSILVER Orders" column.

Any advice on how to complete the cancelling of the order and get my bitSILVER balance back would be appreciated.
