Unable to invent Satellite Dish

Hello, I'll just get to the point. I was with my sim at their job (Scientist) because I needed the Satellite Dish for a challenge I'm currently doing. If I select invent device, I can have Satellite Dish as an option but my sim doesn't recognize me telling her to invent that despite having all of the needed ingredients. I can invent anything else my sim can invent. It's ONLY the satellite dish that isn't working.
