Bugged Trophy

I'm doing the plat of The Sims 4 and have reached skill level 10 in Mischief, but the "Mischief Mastered" trophy doesn't appear. I also tried to reach level 10 with another sim, but nothing. I haven't used any cheats other than the "traits.equip_trait" cheats.These cheats don't affect platinum, though, infact I've already earned a lot of trophies. Please help me. I want to complete the plat.
