5th Generation - Nike plus syncing issues

I have an iPod nano 5th Generation

I have hooked it up to the matrix fitness equipment to record my gym workouts

It has recorded the workout in the history part of the Nike plus section on my iPod

It is recorded under daily totals, and has recorded the days workout

But in workout totals and personal best everything is still showing as dashes

I have synced my iPod to iTunes and it asked if i want to sync my data to Nike plus account but it hasn't taken over any data from today's work out

but i checked within my Nike plus section of the iPod within iTunes and its states my last work out is nothing and my totals are nothing even though i have got workout data for today's date

anyone who can help me i will be very grateful as it is driving me insane 😕

I have the latest version of iTunes (12.1.2) and the latest software version for my iPod (1.0.2) and i am windows based PC
