by 'doesnt show up' do you mean it shows a cardback?

if this is the case, try turning off random rules and selecting specific rules which you are familiar with.

Open will hide the ai's hand cards until the end of the match
Blind will hide any cards that the ai controls that are on the board, until the end of the match (Blind is one of my own new rules)

i suspect this is a prime case of not knowing how a rule works :-p
