Tonight as I was watching the highlights on C4, the narrator clearly said "last week, nominations were cancelled"

Was this a slip of the tongue? Or a way of letting us know they deliberately cancelled them?

Nominations didn't take place due to the task. If they had failed the task nominations would have gone ahead as normal.

I dont understand what you mean Little Tinker

The week that Kate and PJ got to see their family videos and were automatically put up for eviction with no nominations.
Wasnt it speculated that BB 'cancelled' nominations at the last minute to try and save Jade being up again???
Well, the narrator definitely said they were cancelled.

Perhaps I didnt word it very well

No, nothing untoward here.

The housemates passed the 'task' so BB cancelled the nominations.

But how were the HMs supposed to fail? Surely they had no choice in what they did, there weren't going to be any nominations.

Of course they could fail, all they had to do was to refuse to take any of the messages.
