A mistake made in application form

Hi everyone! I applied for a standard fiance visa by myself on the 11th of November. I also had my biometrics the same day. For some reason, i misunderstood the sentence, “does anyone else live with your partner in the house other than his dependents?” I said No thinking that no dependents live with him. It was so careless of me. But he actually lives with his mum and I mentioned it even in the form where we are asked to provide additional information if I want to. My fiancé’s mother own the house and I will be joining them. The house has three bedrooms, common room and a sun room along with a large kitchen and bathrooms. It will not be over crowded at all. We submitted pictures, invitation letter, land deeds, electric bill on her name at the address and WiFi bill on his name at the address. There’s something more. All the documents show her name as “Anne Spencer” but the electric bill has her name spelled wrong and says Annie Spencer instead of Anne. Since they live in Northern Ireland, they have no council tax and water tax so that was the only documents we had at that time so we just submitted somehow. Will these cause any issue and might lead to rejection? Can I do anything to correct the mistakes? Any advice or suggestions will be greatly appreciated.
