Unaswered Question: Did James, Carlos and Logan were not invited to the 1D: This is Us premiere few months ago?

I thought James, Carlos and Logan did not attended the premiere few days yang lalu but they boys of 1D did not invited them only Kendall was invited. A tahun yang lalu at BT Movie premiere they boys invited all the members of 1D at their premiere. So is there conflict of interest is happening?
