Battlestar Galactica - Exodus - Final Five loyalty cards

Hiya. Having the same problem as this thread from 2011 - have added Final Five/Personal Goal loyalty cards to the loyalty deck and drawn them all to hand as a test but have received only basic ‘You are not a Cylon’ in my hand. However, that poster’s problems appeared to come from failing to add the extra loyalty cards into the deck to start with, but I’ve definitely shuffled them in. Any ideas as to what’s wrong?

In fact, when I shuffle the Final Five loyalty cards into the human loyalty cards, when I then click on the human cards to shuffle them into the loyalty deck, when it gets down to five remaining cards in the human pile it will no longer add them to the loyalty deck no matter how many times I click. So I guess the Final Five cards literally can’t be used?
