Appium cant find ID of 2/3 seekbar but all on the same page

I've got 3 seekbar in my app on the same page:

page with 3 seekbar

I am trying to automate my app with Appium and C#, i am trying to move the seekbar by ID. The first one works like expected, but the other 2 cant be located by their id, error message:

System.InvalidOperationException: The coordinates provided to an interactions operation are invalid. (InvalidElementCoordinates)

My method:

public void moveSeekBar(string id, double valueToMove, AppiumDriver<IWebElement> driver)
    {
        IWebElement seek_bar = driver.FindElement(By.Id(id));
        //IWebElement seek_bar = driver.FindElement(By.XPath("//android.widget.SeekBar[@resource-id='" + id + "']"));
        int start = seek_bar.Location.X;
        int end = seek_bar.Size.Width;
        int y = seek_bar.Location.Y;

        TouchAction action = new TouchAction(driver);

        int moveTo = (int)(end * valueToMove);
        action.Press(start, y).MoveTo(moveTo, y).Release().Perform();
    }

And the maincode:

        string exam = "seekbarExam";
        string assessment = "seekbarAssessment";
        string homework = "seekbarHomework";

        noten.moveSeekBar(exam, 0, driver);
        Thread.Sleep(2000);
        noten.moveSeekBar(exam, 0.4, driver);
        Thread.Sleep(2000);            
        noten.moveSeekBar(assessment, 0, driver);
        Thread.Sleep(2000);
        noten.moveSeekBar(assessment, 0.3, driver);
        Thread.Sleep(2000);
        noten.moveSeekBar(homework, 0, driver);

I also tried to get the ID via XPath but obviously its not working because he seems to have a problem with the id.

ID of seekbar

I also used google but couldnt find someone with a similiar problem, maybe someone got a solution?
