Service voucer expired prompt at 9k in the info screen, yet I was told on purchase 18k intervals. Thoughts?

This is something well covered in several previous posts, including here:

(basically for Fiats made after about January 2014 onwards, Fiat halved the frequency of service visits, although the first, third, fifth etc are mostly just 'visual checks' )

In which I participated..... A call to the dealer is forthcoming I think!
