Unwanted Pace Alerts when using a Course on an outdoor run

I used the Course feature on my FR265 for the first time today and it worked great. There was one feature however that was driving me crazy. It kept on giving me alerts that I was running too slow. I did not (and have not at any time) setup any pace alerts. I did however setup a max heart rate alert for the run. I did notice that there is a PAcePro section in the course setup which I did not adjust. Just kept the default settings.

Any ideas on how to switch off these alerts and how to debug?
