"Letter from relatives confirming I or my partner lived with them"

Hi guys, I applied for my extension and got my approval. Just wanted to let you know about this letter came up in my document list, even though I didn't select any options about that or neither of us lived with someone else. I've done my research and write up a cover letter explaining that, gave my biometrics on Friday got the approval today. So no need to worry if that came up on yours, just write a cover letter, it's fine 👍
