Clear numerical Textbox and send Value - C# Selenium

Question

I have a numerical Textfield. I can fill this Textfield with Sendkeys ...

This is the HTML Code.

HTML-Code:

<input class="form-control busy-disabled" 
id="entry-lots" 
type="number" 
value="1" min="0.01" max="20" step="0.01">

But first i want to clear this Textfield. If i send a *.Clear() it will result in a new value "0.01" ... whatever was inside before.

My Code is:

IWebElement element = webdriver.FindElement(By.Id("entry-lots"));
element.Click();
element.Clear();
element.SendKeys("0.02");

This short lines will result in the Value "0.01002" and not in "0.02" as i need.

Any Ideas to help me out? If interesting: I am using a Windows-Forms Program.

The Webpage is: https://eas.forexsb.com/

Navigate in the blue Top Line to "Generator" and switch there to "Reactor". Down in the "Reactor" switch to "2. Strategy properties".

The Field "Entry lots" will give my problem.

Using this code you should get the expexted results

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

var driver = new ChromeDriver();
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(20);
driver.Navigate().GoToUrl("https://eas.forexsb.com/");

var menu = driver.FindElement(By.XPath("//a[@id='acquisition-toggle']"));
menu.Click();

var reactor = driver.FindElement(By.XPath("//a[@data-name='Reactor']"));
reactor.Click();

var collapse = driver.FindElement(By.XPath("//a[@href='#collapse2']"));
collapse.Click();

var input = driver.FindElement(By.XPath("//input[@id='entry-lots']"));
input.Click();
input.Clear();
input.SendKeys("0.02");
