Why does my team leader treat me more harshly than my colleagues?

I have a colleague who seems to never really communicate to important questions or group discussions especially about choosing time slots for lunch and I’m getting blamed for taking an earlier slot than him but it’s not fair because this guy never tells the rest of the team about choosing a time slot or says anything. Some how the management team seem to think his behaviour is cute and funny because he’s from another country/ race

This particular colleague also didn’t fully process an order and left part of the order just lying in another box he just didn’t tell the other staff and I seemed to got the blame and my team leader just gave me a massive sigh towards me
