Bug: selected segment background color persistence

[mwurm93]

Thanks for your awesome library! I'm running into a bug where the selected segment background color persists sometimes after moving it to another segment (see below). Please help!

Code for implementation is below:
let segmentedControlTitles = ["Assistant","Itinerary","Chat"]
segmentedControl = TwicketSegmentedControl(frame: CGRect(x: UIScreen.main.bounds.width / 2 - 135, y: 20, width: 270, height: 40))
segmentedControl?.setSegmentItems(segmentedControlTitles)
segmentedControl?.delegate = self
segmentedControl?.segmentsBackgroundColor = UIColor.clear
segmentedControl?.isSliderShadowHidden = false
segmentedControl?.backgroundColor = .clear // This is important!
