​cTrader Desktop 4.6.2 bug - On backtesting MTF Range bars, the higher bars does not updated

I would like to report a bug.

cTrader version: 4.6.2.12995 (latest)

 cTrader Automate nuget package: 1.0.6 (latest)

Using below example cBot, you can see that in case of BackTest on Range20 OpenPrices from server option, the higher timeframe bars does not update!
But if you run BackTest on Tickdata from server, then everything is correct.

using cAlgo.API;
using cAlgo.API.Internals;
using System;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter("Current Chart TimeFrame", DefaultValue = "Ra20")]
        public TimeFrame TF_1 { get; set; }

        [Parameter("Higher TimeFrame", DefaultValue = "Ra200")]
        public TimeFrame TF_2 { get; set; }

        private Bars _currentChartBars, _higherTimeFrameChartBars;
        protected override void OnStart()
        {
            _currentChartBars = MarketData.GetBars(TF_1);
            _higherTimeFrameChartBars = MarketData.GetBars(TF_2);
        }

        protected override void OnBar()
        {
            if (Bars.LastBar.OpenTime > new DateTime(2023, 1, 27, 12, 0, 0)
                && Bars.LastBar.OpenTime < new DateTime(2023, 1, 27, 16, 0, 0))
            {
                // This is the current chart timeframe which is Range20. This is always right.
                Print("Range 20: " + _currentChartBars.LastBar.OpenTime.ToString("yyyy-MM-dd HH:mm:ss.fff"));

                // This is the higher timeframe
                // Wrong --> when used with Range20 openprices from server option. (Note that this is higher timeframe and not chart timeframe.)
                // Right --> when used with EveryTick from server option.
                Print("Range 200: " + _higherTimeFrameChartBars.LastBar.OpenTime.ToString("yyyy-MM-dd HH:mm:ss.fff"));
            }
        }
    }
}
