Unable to unlock lutscher route achievement

Am now on the lutscher route whicb is stated in the game article and interface to be 13.7km. See link here https://support.zwift.com/en_us/zwift-worlds-and-cycling-routes-Sy2_gxTGB#Innsbruc

I am now 18km in but the route achievement has not unlocked for me?

This has happened several times for me on several occasions and i understand that this is sometimes due to a lead in distance?

I am new to zwift and frankly i dont quite get this.

Is this a bug? Why is the route achievement not being unlocked although I fulfilled the stated distance? Where can i see the real route distance requirements? What is the rationale in displaying a distance that does not appear to tally?
