Tilt and turn doors?

I have just had my tilt and turn doors and Windows intstalled but I have a query. When I tilt the door or the window, the final position it is kind of done in two steps. although I do not think I explain myself very well. I mean it feels like they do not just glide to the final position but they kind of slightly click before they final position, like you need to apply a slight force. I did my best to describe it as best as I could .

 Any ideas ?
