re adding a few CT10 sensors in the S62

This week i noticed that 3 out of the 14 CT10 sensors are not responing properly. I removed them from the list in the watch with the idea to add them again. But going into the menu the option add a sensor is not showing So, i'm stuck with only 11 clubs. And my putter, driver and Pitsching wedge are out. How can i add them again?
