Reset TP set manually via calculator

Hi - how can I remove the fitness signature set with the calculator? My TP/LTP seem to be quite high. too high. “Played around” with the fitness signature calculator but now I do not know how to remove the signature set manually.
Thanks.

You can manually set the signature using My Fitness / Advanced tab. You can’t remove it. You’ll need to set it to some values likely those from your last activity. Hope this helps.
