bugs in LoadMoreHistory()

cTrader Version 4.8.30

If have the following code:
      protected override void OnStart()

      {

         //mMyBars = MarketData.GetBars(TimeFrame.Hour, Symbol.Name);

         var mMyBars = Bars;

         Print(mMyBars.Count);

         var loaded = mMyBars.LoadMoreHistory();

         Print(loaded);

         Print(mMyBars.Count);

      }

Bug1:

When    [Robot(AccessRights = AccessRights.None)] AND backtesting is NOT in VisualMode the following is printed after backtest start:

29/01/2024 01:00:00.000 | CBot instance [Empty, EURUSD, h1] started.

29/01/2024 01:00:00.000 | Symbol 'EURUSD h1' cached data not available or corrupted.

29/01/2024 01:00:00.000 | Symbol 'EURUSD h1' cached data cleared.

29/01/2024 01:00:00.000 | Failed to get symbol 'EURUSD': Symbol not found or has no quotes.

29/01/2024 01:00:00.000 | 0

29/01/2024 01:00:00.000 | 0

29/01/2024 01:00:00.000 | 0

29/01/2024 01:00:00.000 | CBot instance [Empty, EURUSD, h1] stopped.

If Visual Mode is on OR    [Robot(AccessRights = AccessRights.FullAccess)], the following is printed after backtest start:

29/01/2024 01:00:00.000 | CBot instance [Empty, EURUSD, h1] started.

29/01/2024 01:00:00.130 | 201

29/01/2024 01:00:00.130 | 0

29/01/2024 01:00:00.130 | 201

31/01/2024 12:24:20.104 | CBot instance [Empty, EURUSD, h1] stopped by user.

Bug2:

As it can been seen, LoadMoreHistory() has absolutely no effect.
I need more than just 201 History bars at the start of the bot!
