All booking engines have rules for names, especially for shortening them, and check-in staff and Immigration officers are well aware of them. A major problem is that there are only a limited number of characters on your ticket, and boarding pass, for your name and often it has to be shortened to fit.

You have absolutely no need to worry. QR will not change your ticket name without you cancelling and purchasing new tickets at the current price. Even if they did the booking engine would probably remove it and you are back where you started!
