Examples in lecture are not in line with those in lecture notes

Hi ,
I used the lectures on chapter 7 – IAS 32 and IFRS 9 financial instruments to go through the lesson and at the end of lecture one of chapter 7 I found the example discussed in the lecture is something called PX and there is a different example in the lecture notes provided.

I found the same issue in a previous lesson ( I cant remember what the exact lesson was ).

Please guide me through this issue so as to how i can continue to finish chapter 7 and any possible issues like this that would arise later as i proceed.

Thanks in advance ,
Lochana Fernando
