huge error on calculation swap between visual mode an non visual mode version 4.8.21

Dear cTrader team,
During the backtesting of a cBot, I have noticed a significant difference between visual backtesting and silent backtesting. The difference concerns the calculation of the swap. As you can see in the visual version, in the historical data, the swap is not calculated, whereas in the non-visual version, it is. This creates a quite evident discrepancy in net profit and in the strategy decision when using the visual mode. Additionally, after downloading version 4.1 and adapting the code to the net.4.x version, I encountered the following errors:
Error: Unknown Guid format.
Error : No algo source file was found in "Remora Ultima 2023.csproj".
How should I proceed? What solutions do you have? Thank you for your assistance.
as you can see it has passed 12 days and 0 swap in visual mode
in not visual mode, it calculate the swap
visual mode up
not visual mode down,

"Guys, unfortunately, a serious error keeps occurring. During the backtest, the net profit calculation is incorrect, as you can see from the image, the net profit is completely wrong when looking at the open positions. What should I do to avoid this error?"

Dear giuseppealessioferrandes,
Can you please share a cBot code that would allow us to reproduce this behavior?

Certainly! I've created a small algorithm to demonstrate where and how the error occurs. The algorithm is designed for use on the EUR/USD daily time frame. In practice, I open a position, and for every certain number of pips of loss, I add volumes to the position to average it. The issue is that after a certain number of added volumes, I encounter an error in the unrealized net, and it appears not to take the swap into account. The same error also occurs in the equity calculation during backtesting, but as you can see in the last image, it includes all the swaps when I close all positions.
