I wondered whether the mother ship house has decided it needs to make savings, and put Sr Ursula in charge to do just that. So no matter what her personal inclinations, she feels obliged under her vow of obedience to do so. I expect by the end of the series Sr Julienne will have convinced her of the error of her ways, and together they'll get things sorted with HQ.
Has Patsy gone for good? I thought she'd be out for a few episodes then re-appear.
