All of my programmatically created buttons work except for one

Code Block 
for image in 1...10 {
      let imageName = String("image\(String(image)).png")
      let imageToDisplay = UIImage(named: imageName)
      let catagoryButton = UIButton(type: UIButton.ButtonType.custom) as UIButton
      catagoryButton.setBackgroundImage(imageToDisplay, for: .normal)
       
      let xCoor = 20 + 60 * CGFloat(image - 1)
      contentWidth += 60
       
      catagoryButton.frame = CGRect(x: xCoor, y: 10, width: 40, height: 40)
      catagoryButton.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
      catagoryButton.tag = image
      catagoryScrollView.addSubview(catagoryButton)
      print("This Buttons tag is \(catagoryButton.tag)")
    }
    catagoryScrollView.contentSize = CGSize(width: contentWidth + 20, height: 60)
