It is non crossed but it consider as crossed

My code is as below:

if (longPosition.Count() == 1)
            {
                if (SMAShort.Result.HasCrossedBelow(SMAMedium.Result, 1))
                {
                    int newvol = System.Convert.ToInt32(Symbol.NormalizeVolumeInUnits(Symbol.QuantityToVolumeInUnits(lot * (1 - (TP1Percent + TP2Percent) / 100)), RoundingMode.Down));
                    ClosePosition(Positions.Find("Nasser Reverse" + Symbol.Code));
                    BuyTP1Flag = false;
                    if (shortPosition.Count() == 0 && SMAShort.Result.HasCrossedBelow(SMAMedium.Result, 1) || SMAShort.Result.HasCrossedBelow(SMALong.Result, 1))
                    {
                        //                    lot = VolumeCal(StopLoss);
                        if (!(SMAMedium.Result.Last(1) < SMALong.Result.Last(1)))
                            lotlot = Math.Round(0.5 * lot, 2);
                        ExecuteMarketOrder(TradeType.Sell, Symbol, Symbol.NormalizeVolumeInUnits(Symbol.QuantityToVolumeInUnits(lotlot), RoundingMode.Down), "Nasser Reverse" + Symbol.Code, StopLoss, null, 0.5);
                        Print(SMAShort.Result.Last(1), "    ", SMAMedium.Result.Last(1));
                    }
                    BuyTP1Flag = false;
                }
            }

Actually based on printed information SMAShort did not have any cross with SMAMedium, but it returns true as confimed cross. please advise

first value is SMAShort(1) and second value is belong to SMAMedium(1),as you see there is no cross, but cbot closed the position
