Hi bbkoopsta,
I had a similar problem with DGB withdraw. It says they can take up to 24 hrs which is about how long I had to wait before they put my pending withdraw back in my account. It appears from your screen shot that you have open orders with your AMP. Cancel those first and you will be able to sell.
If you have any problems withdrawing coins share it here. I just kept trading my DGB, not sure why they would not process my withdraw still.
Good Day
Thank you so much, in fact reading your comments guys made me realise that i left my coins on the order book without realising that! now everything is clear thanks a lot, by the way i had a similair problem withdrawing my BTC i had to open a support ticket just to get it done! and the response was fast tbh!
