Tarot Card Issue

I'm trying to complete the Tarot Card collection and have gotten all of them except for the Strength card which you get by delivering Ghost Essence to the Ghost Host Order Member. My Sim is a ghost and has had no problems getting the Essence but when I try to deliver them, the option isn't available. Instead I keep seeing "Offer to Help with Favor" which shows the exact thing I am missing. Is this a glitch or just a problem because I'm already playing with a ghost sim instead of making a sim go into the bog?
