CT 4.2 - Reverse Order Bug

Hi,

There seems to be an issue with reversing a trade direction using cTrader beta 4.2, I ran this basic test.

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class ReverseTest : Robot
    {
        [Parameter(DefaultValue = "Hello world!")]
        public string Message { get; set; }

        protected override void OnStart()
        {
            ExecuteMarketOrderAsync(TradeType.Buy, SymbolName, 50);
        }
        
         protected override void OnBar()
        {
            foreach (var position in Positions.Where(x => (x.SymbolName == Symbol.Name)).Where(x => x.TradeType == TradeType.Buy))
            {
                position.Reverse();
            }
        }
    }
}

What happens is that the order opens for BTCUSD with 50 lots, but when the candle closes (1-min TF) and the position is reversed, a notification states that the order was abnormal and attempted to reverse with double the original trade size.

I also tried ReversePosition(position), and had the same issue.

This works ok with 1 lot
