While practice varies, it's perfectly normal for a name on a boarding pass to be "LAST/ FIRST MIDDLE MR", So "Mr John Jack Smith" appears as "SMITH/JOHN JACK MR". That seems to be exactly what has been done to your name.
I wouldn't worry about it. Airline staff are almost certainly familiar with a wide variety of international naming styles, and if they ask a brief explanation will probably sort it out.
