I have assigned so far13 clubs: D, 3H, 3W, I5-9, and 4 wedges.
Today I have tried to assign a new one I4 - and there is no such option. There is no space on the list for the 14th sensor.
Even if I try to reassigne a former sensor to I4 there is no such choice in menu 
What to do - tehy sell set of 14, and have space for 13? Can't belive
