Chart Control Remains on the Chart even after bot has stopped

Hello Spotware,

I'm having an issue in which using Chart.MoveControl() for controls attached to the chart using the price, index/date overload makes it impossible to remove it afterwards, even after the bot is stopped, it remains there.

The only way I have to circumvent this is not using Chart.MoveControl() altogether but rely on add/remove repeatedly.

I think there's no other way to remove a Control and it's an issue, if I'm doing something wrong, please let me know.

Here's the sample code and video:

cTrader - 2024-08-25_17-20-13 - TechSmith Screencast - TechSmith Screencast

using System;
using cAlgo.API;
using cAlgo.API.Collections;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;

namespace cAlgo.Robots;

[Robot(AccessRights = AccessRights.None, AddIndicators = true)]
public class RemoveButtonIssue : Robot
{
    private Button _button;
    private int _counter;

    protected override void OnStart()
    {
        _button = new Button
        {
            Text = "Click Me",
            Width = 100,
            Height = 50,
        };
            
        Chart.AddControl(_button, Bars.Count - 1 - 10, Ask);
            
        Timer.Start(3);
    }

    protected override void OnTimer()
    {
        //this seems to work fine
        // Chart.RemoveControl(_button);
        // Chart.AddControl(_button, Bars.Count - 1 - 10, Ask + ++_counter * Symbol.PipSize);
            
        //When it is moved, it will not be removed even after stopping the robot
        Chart.MoveControl(_button, Bars.Count - 1 - 10, Ask + ++_counter * Symbol.PipSize);
    }

    protected override void OnStop()
    {
        Chart.RemoveControl(_button);
    }
}

Regards,
