It wants me to pay for the Self-employed package even though neither my profile or my wife's shows self-employed. Why might it want to to buy self-employed?

My wife does her business taxes separate to cover the business. She takes a T5 for all of her income, adding up to under 25k. Adding this also seems to move our return from getting 2k back to paying 2k! I just have a T4. What am I missing?
