[BUG THREAD] The Sims 4 CAS Demo

Okay, so I have the demo all set up, and I've even made a household already. I went into the community to look at what others had already shared and wanted to pick up a sim or two to tweak or just overall mess with. I can save the sim into my library, but then when I pull up the sim and hover over the wrench icon it gives me the following message: "Cannot apply Gallery templates in the game mode". Any idea what I can do to fix this?
