Yes
We would not generally go ahead and start an upgrade on someones site. While I understand you are unsure as to why there was a question there, this doenst mean the question wasnt valid.
You asked how to upgrade, I asked what message you were getting. You stated it was giving you a message to add a field you dont believe it should be asking you, and I asked if it was causing an issue when you click to add that field (ie, can you continue). I believe these are quite reasonable questions.
