Sims who Dislike Mischief Autonomously do Mischief

I have a sim who is Proper, dislikes Mischief, and she still Asks Due Date about three minutes into any conversation. I have to click it out of her queue about 30 seconds into any conversation if autonomy is on. She is a home designer and I cannot leave autonomy on or she will immediately be ejected from the lot for being "inappropriate" while speaking to clients and gets all kinds of debuffs from her own actions. As vyvexthorne said, everyone puts their foot in it occasionally, but it is really annoying to try and make a sim who is purportedly none of these things and still uses Ask Due Date and Lie About Career autonomously as their default social action.
