instead of sendkeys last copied item from clipboard is getting entered in the element

In my application I have an email field and I'm using sendkeys to send an email address, but instead of sendkeys selenium inserts the value from clipboard. Do anyone faced this issue?

code:

WebElement email=driver.findElement(By.xpath("//div[@class='auth-container']//input[@type='text']");
email.sendKeys("sample@sample.com")

since Id is dynamic I have taken xpath from parent container
