Trainer Error (Incorrect Category)

I recently did a Ride on my Elite Zumo which gave my FTP nearly 60 points above what i was expecting (270). My FTP usually is around 200-230 depending on the time of year. Anyway i have since upgraded to a brand new Kickr Move and done a Ramp test (203W) this si about where i was expecting to be. However, this intiial issue has put me into Cat B. Is there any way i can remove this outlier ride? I have since deleted the ride from my Zwift and Strava in hope that it doesnt mess up my data

Email and explain what happened.
