Unfortunately, on PS3, console commands aren't an option. Have you tried a couple of different things like fast-traveling to another location or reloading a previous save before the glitch occurred? Sometimes, these glitches resolve themselves with a bit of in-game time passing. If those don't work, focusing on other quests or storylines might trigger a reset upon returning. It's frustrating, but sometimes the game needs a bit of time to recalibrate. And to get a better understanding of everything I think you should search https://www.playoholic.com/ for the game manual. I think you'll find it helpful. Good luck.
