Wants and fears keep showing up after I restart the game..

It also switches back on every time you go in and out of CAS. Another occurence is when your sim first gets a boyfriend or girlfriend and usually the "want to woohoo" switches it back on. When you move another sim into your household they can often have wants and fears switched on even if you main sim has it disabled. Frankly I'm fed up with it and wish the devs hadn't bothered since they've made such a slapdash job of it.
