System states that I have resigned two correspondence games, but I did not log on until later today

I have not logged into my correspondence games until this evening, but it is stated that I have resigned my games earlier today. I did not resign my games, as they are in early stages. I did not overstep the time limit, and my account is not flagged. Is this a bug or is there another explanation for this please?

I think they have been auto-resigned by the server. Please visit lichess.org/appeal
