Approach CT10 and S60 not allowing Putter to be added

My S60 will not allow me to pair my Putter and Lob Wedge - all other clubs have been paired and are working.
I have set up all my clubs in Gamin Connect under the "Gear" option, however my Putter and Lob Wedge does not sync across to my S60.
In addition there is not option to "add new Sensor" on my S60 even though only 12 clubs are paired.

Have anyone else experienced this ?
