If your buy limit order is in "Inactive" status, you may not have a sufficient cash balance for the order to execute, or you may have since removed your linked payment method that was selected when your order was created.
If your sell limit order is in "Inactive" status, you may have sold the metal ounces that were designated for liquidation when you originally created the sell limit order. In either case, you may edit order delete limit orders from the limit order dashboard.
