Wrong model number on my bike?

I don't know if I'm being stupid but I just bought a Ninja 300 ABS 2016 and I was checking out the compliance plate on the bike and it says the model code for the bike is ER300B, I looked it up online and it says thats meant to be the model for the Z300, but the bike is most definitely a Ninja 300, it's registered as that and the engine code on the registration papers is EX300AEA*****.

Is this an issue or am I just overreacting? I'm in Australia if that helps.
